SL 28-70 2.8 ?

That lens is not even weather sealed if I am not mistaken. That is where the excellence ended for me and I picked the 20-60 Panasonic.

Giving that the wide primes were/are much delayed I could see Leica surprising us.

I think I would prefer a smaller 28-70 versus over the 24-90. That to me would make more sense than just a 24-70 that may be nearly as massive as the 24-90.

The original quote included mention of the light weather sealing. The rest of the review is comparing mainly to the Tamron 28-75, which doesn’t have the best build quality or image quality. These lenses are prioritizing size and weight and price, which offers other trade offs in IQ and build.
 

Leica tends to shoot for IQ and sometimes size and weight, though price tends to be much higher.

Sigma 24-70/2.8 is excellent.  I got it last year and enjoy it as a single walkaround lens.  It would be hard to justify a 5x price for a Leica version that starts longer.

all Leica lenses are 5 to 10 times more expensive 

Ill wait for the Leica 28-70  , and  I prefer a 28-70 than a 24-70

The Sigma 24-70 is also 830g and has a big footprint with an 82mm filter size. 

By comparison the Sigma 28-70 is 470g and 67mm, and it's more suited for a full walkaroud day out, if you're willing to sacrifice quality and the extra reach for weight and size (I am). 

The Leica could sit somewhere in between, high quality and small size. Basically we have plenty of options to choose from depending on your needs

Leica will launch (probaly this summer) a 28-70mm Vario SL f2.8. It is not yet confirmed if it is 24 or 28mm. It is a SIGMA design optimised by LEICA (coating & mecanical design. The price will be lower than the other SL lenses.

Much of the sub assemblies for Leica lenses and bodies come for Portugal these days.

Not just these days. The Leica Portugal factory was established in 1973.

I’ll add one more note regarding the review by DustinAbbot.net. In the Sigma 28-70 review he noted the nice build. I haven’t handled that lens but I do own the Sigma 105 Macro DN lens and he reviewed that as well. 
 

His 105 review mentions:

“The lens feels great in the hand and looks premium on camera.”

“Pros:

• Excellent build quality”

 

I can’t agree with the lens feeling great in hand or looking premium on camera. It looks and feels cheap relative to my Leica lenses, and relative to the Nikon lenses I used to shoot. Having the “excellent build quality” as the first pro for the lens doesn’t seem right to me either. I consider the pros for the lens to be IQ, size, weight, and price. Build quality feels like a con to me.

Define build quality. Everyone has their own perception of what good build quality means.

Many people associate density with build quality so a lens that appear heavy for its size is considered higher quality but this is misleading since your can easily add weight to something without actually making it objectively better.

Others associate metal construction as being of higher quality compared to plastic. But generally speaking aluminum will dent easily whereas plastic will not. Plastic can get scratched but so can all metal finishes. Metals will expand and contract based on temperature and can potentially throw off the lens optics if not designed well whereas specially engineered plastics can avoid this problem altogether.

Build quality has subjective and objective qualities.

My point was that referencing what a reviewer states about build quality is not as useful as testing the lens yourself to see if it meets your needs. My opinion of the Sigma build quality is different than the reviewer’s. His comparison for the Sigma 28-70 was a Tamron lens. If he had compared to a Sony GM or Leica SL lens, the results would likely be different.

Funny I haven't even noticed they've made a smaller Sigma SL zoom, 28-70!  I got the 24-70 and it's awesome.  The 82mm filter size is in line with the S lenses and the 24 width is radically wider than 28.  The weight feels about the same as APO primes.

In terms of build, the excellent quality is the first thing you notice.  So far I got that zoom, the 85/1.4 and the 24/3.5.  The aperture rings, AF/MF switches, metal hoods, and even a magnetic lid on the 24 scream quality.  Leica APO primes are just tubes with fly-by-wire rings om them, quality tubes, nothing dangling inside, but not oozing "better build" in any way over Sigmas.

I have a number of Sigma L mount  lenses which supplement my Leica L mount lenses. I fully agree with you regarding all the attributes of the Sigma lenses, (especially the aperture ring which I'm a huge fan of),  so much so that I find that a couple of my Leica L lenses seem to be spending more time on the shelf while my Sigmas are getting more use on the SL2.

I've checked out B&H Photo and the Sigma 28-70 for L mount is not available (not backordered, not new product coming soon, not preorder).  What's up with that?

It was recalled because of ghosting issues, but in the meantime it got fixed last week or something like that. It should be available again. It's listed as preorder on Wex:

Here's Sigma's official statement:

I'd be surprised if we see this from Leica. Peter Karbe has said you compromise too much image quality in zooms with a constant aperture.
