Whatever they say, staying out of e3 doesn't make sense in my opinion, really.. Presence is always presence and even though we can discuss if e3 is still relevant, the thing is, their competition will be there and it's still has a lot of audience. so, they can say they don't go there because they don't want to spend money or they've got nothing to show.. that's sorta fair, but still, they could survive there with 1 big game only and i don't think money's a problem for a corp like them.
Unless we know what their plans its hard to say.
They dont need e3 to show stuff, especially nowadays with how we all access info.
