Up to now, it seems that at least publicly available, "reliable" rumors point more towards a new mount and an APS-C-sized sensor. So, it should be too early for the anti-m43 fraction to worry
. On the other hand, it may be useful to keep in mind the risks and drawbacks of introducing a new mount. So, "Pentax EVIL NC-1 has smaller sensor than APS-C - your opinion?" in a way is related to the question "Pentax EVIL is supposed to use another new mount - your opinion?".
Some comments regarding...
Quote: really small sensor
Comparing [(m)43 with APS-C] and [APS-C with FF], the same or at least very similar arguments may apply.
Sensor sizes (crop factor):
FF: 36x24mm^2 = 864mm^2 (1)
APS-C: ~23.6x15.7mm^2 = ~370mm^2 (~1.5)
(m)43: 17.3x13mm^2 = 225 mm^2 (2) [same size, different flange focal distances]
Regarding the lenses, would't you like e.g. (simply) scaled down (1:2) FA limiteds (31/1.8 -> 16/1.8, 43/1.9 -> 22/1.9, 77/1.8 -> 39/1.8), FAs (20-35/4 -> 10-18/4, 24-90/3.5-4.5 -> 12-45/3.5-4.5, 35/2 -> 18/2, 50/1.4 -> 25/1.4) or even D(F)As (50+100 Macro -> 25+50 Macro, 60-250/4 -> 30-125/4, 200/2.8 -> 100/2.8, 300/4 -> 150/4) etc.?

As I understand it, the (first) mirrorless from Pentax should fill the gap between APS-C DSLRs and P&S cameras. Thus, it would also have to be priced accordingly. Additionally, if Pentax finally introduces a FF, it imho really should be a camera with a PKAF2 mount!
