4. Heavy Rain gameplay demonstration

Heavy Rain is one of those games that gains hype for doing nothing. We've seen a tech demo showing a woman in a kitchen, a handful of screen shots and some low quality behind the scenes development footage, yet the game is seen by many PS3 owners as one of the console's most important titles. It's hard to know what to expect from Games Convention, but we really want Sony to release some proper gameplay footage so everyone can get a good look at the game. We won't be happy if we get another God of War 3 reveal and are left with a short CG trailer telling us about a game we already knew existed.

3. God of War 3 gameplay

As far as Games Convention wishes go, this is right up there. E3 promised so much yet delivered the absolute bare minimum when it came to God of War. Having already had the game confirmed we needed to see the game in action, yet all we got was a rendered trailer. It might be asking for a lot to get the first in-game trailer for one of Sony Computer Entertainment America's biggest PS3 titles at a European event, but after E3 Sony needs to dazzle gamers with actual gameplay. The time for teaser trailers is over.
