I am getting some more confirmation that indeed Sony has organized a major Journalists and Blogger gathering for next week. This is by far no 100% reliable proof that there might be a product announcement. But for sure there is a major effort from Sony to get them all together.
Only one source which has been sometimes correct in the past (but also wrong 1-2 times) said that for sure Sony will announce new lenses. Here is his message:
Big Sony E-mount announcement is coming very soon. Lenses for sure, maybe APS-C camera too.
Still, I cannot rank this rumor with SR4 or SR5 yet.
All I know with 99% certainty is:
1) that No A7sIII is coming yet
2) that the next E-mount camera should be announced soon and it should be a High End APS-C
3) 135mm f/1.8 GM should be announced too along a new APS-C lens
