I've been thinking about my previous predictions and I wanted to have a more realistic one in case things don't turn out as I thought.
Keep in mind I'm not an insider even though this stuff sounds like a done deal.
PS4:
1. Suspend/Resume. I know it's not a game but it's a nice feature.
2. Uncharted 4 E3 demo. It's not a full game but there are a lot of different ways to play and March is a short month.
3. Surprise release for Guerrilla Games secret RPG to end all RPGs.
4. Halo Master Chief Collection
I haven't heard anything specific on PS3/Vita. Take that as you will.
EDIT: WAIT, Leonard Nimoy died!? FUCKING HELL. RIP.
