Just wondering what everyone thinks. The PS3 still has TLoU, Beyond 2 Souls, and GT6 coming out after E3. How much time do you think Sony will spend talking about the PS3 at E3? 

Also I'd ask same about the Vita 

Hopefully smooth and quick but not rushed

Just give us our last batch of games, release dates, trailers and the $70 price cut to $199 and i'm good

Or they can save the price cut for september

25%-PS3
25%-Vita
50%-PS4

45% PS4-Destiny, MM New IP, GG New IP or SSM New IP, show off a little footage of DriveClub, inFamous, Killzone and Knack. etc...
35% Vita- IDK?
20% PS3- Definately going to show GT6 and Beyond Two Souls, I'm not sure if they will show The Last of Us since it release 2-3 days after. Doubt they will show Puppeteer or Rain.

Do we know how long the conference will last? Is it gonna be just an hour or will it be 90mins to 2 hours?

The conference is 3 hours long. I'd say they'll give each console an hour each.

Pa3 should get a good showing IMO

Its 3 hours this year 6pm to 9pm PST. 

Anyway i hope it is ~30mins PS3, ~45mins Vita, ~1 hour 45mins PS4. 

No conference has ever been more than 2 hours. 3 would just drag on far too long.

OT: 

I imagine 20-25% will be dedicated to the system of the PS4 itself, not the games. 

Then we'll have 30% for the PS3

20-25% for the PS4

20% for the Vita

Id rather it be aimed more around the PS Vita/PS4, but there will be talk of the PS3 games etc and possibly a price cut.
