I hope Sony makes PSX an annual thing. Couldn't go this year but it looked like a really fun event. I'd like to go next year.

It is an annual event.

In one of the panels they said they're stil deciding on whether or not to make it annual. 

IGN says its the first annual PSX event.

It would make sense to make it annual and ditch E3. All PS exclusives and multiplats with exclusive content on PS would get more attention that way.

I don't think they should skip E3, way too much media attention to ignore. I do find it impressive that Sony actually had 4 press conferences this year. Microsoft had two and Nintendo only had one. Though they also do the Nintendo Directs.

They can attract the media attention to PSX, make it a grand event. But what makes this better is that the conference isn't limited to 90 minutes, its upto Sony to make it as long as they want. That gives them a lot more time to properly show-off their games.

Besides PSX will give the limelight only on PS exclusives, while during E3 attention is divided among the multiple conferences.

LittleBigPlanet 3 is wonderful. I can't recommend it enough.

Looks so good.  Really tempted to dive in now
