Oh yeah, they will probably will talk about PSVR.
It will probably be:
-Talk about overall PS4 sales/price cut
-Introduce NEO and few games/strategy going forward
-Show final things about PSVR and their strategy going forward with it
-We have more to share with you in the coming months
-End
They still have TGS, Paris games week and PSX to show off more games so I doubt they will go to deep with that at this meeting.
It sounds like you don't expect it to be released until early 2017.
The prevailing thought is, because Sony is revealing Neo in September they need to launch it this year, or risk hurting PS4 sales. I tend to agree with that.
