There certainly will be some significant (though probably not extremely significant) announcements as PSX, as there always are.

I don't care when they announce them, but I hope that sometime soon we hear about some new PSVR stuff. I'd like to get a sense of whether they're going to give it real support going forward. One has to worry about that with Sony.

As for Vita, we already know where it stands - forgotten by Sony, fading from everyone else's memory. They're not likely to announce an "official" retirement for it though.

I think they will stick to their already working format:

Show 3 games that will blow people's minds every E3. A combination of revived from death, sequel long forgotten and a classic remade.

I can see PSX showing more niche / AA Indie games as well as showing more gameplay and features from games already announced. Probably some new f2p games too.

Well..i've only caught up with PSX last year, so my thought process is that they would hold back games for PSX because they have to remind us as to why their pitch with VR is legitimate. Thats all I am saying. It gives them room because they have so much to show. Not only that, but some announces might be ready to be revealed by that point.

LOL I think I worded it wrong, but bless your heart still. I just feel like Sonys list of games is too large and they are going to have to force some new reveals back. I mean more than last year.

The only PSX that i've seen was in 2016. 

Interestling. So you think that if they should hold back on VR and secondary devices in favor of laying out their competitors at E3? You might be onto something. Gives us something to converse about and speculate because we already have educated knowledge of all of the gameplay trailers that we can expect. I just cannot wait. 

True, but i've only seen one live which was last year. Forgive me for not knowing that. Its just that last gen PSX made so many waves that people started to notice. 

I think E3 will only have Bloodborne 2 as announcement and lots of release windows and trailers and possibly the new Sucker punch game. At PSX I expect more news on matterfal and something by Japan studios maybe in collaboration with Capcom in the form of deep down.

Sony is good at showing things way too early...

- Death Stranding: announced at E3 2016, we haven't even seen gameplay yet or what kind of game it will be.
- Final Fantasy VII Remake: announced at E3 2015, but they only recently entered the development phase...
- Shenmue III: announced at E3 2015, we haven't even seen gameplay yet.
- Dreams: announced at E3 2015, haven't seen much of it since.

I don't think they save anything, they're going to announce games appropriate to the conference. Most of their game big games will be announced at E3. TGS is completely shit now, and I don't think we'll get a Gamescom/PGW because they'll probably just make PSX big again like they did last year. And of course announce games when they're actually able to, ie if a team can get a trailer/reveal ready.
