If I recall, last year they announced a few Vita games before E3 and then E3 came and there was nothing new shown at all.
So let's not get our hopes up. Sony has repeatedly shown that they are incapable of learning from their mistakes (as have many other companies) so I will keep my expectations low.
I remember it being several big PS3 reveals in the month leading up to E3 which led this board to assume the actual E3 event would be focused on the Vita. That didn't happen. Only a few smaller titles for the Vita were announced in the month before E3.
