First question: Is it going to be a replacement for X1?
Second question: Is it going to be an additional camera besides X1?
My answer (my dream): I would like to keep my X1 and I don't want a replacement but an additional X (X2?)
My future camera is exactly like X1 but wider lens like 24 or 28 mm (35mm eq.) with f:2.0 lens.
If it will be faster, it is desirable of course. But an X with the above lens would be my dream and it will be an additional camera besides my existing X1.
