*cue 45 minute blowout on Sony All Stars*
No that will be the week before E3.
This thread is something special, I love my Vita there is no doubt about it, but I really don't see why it and the 3DS can't co-exsist. Despite them both being handhelds I don't think that they would automatically appeal to the same kind of audience for a variety of reasons.
I think the three big conferences are going to shine light on Vitas future greatly, if Sony shows up to all three (E3, Gamescom, and TGS) and ignores, or treats the Vita lightly, then yeah it's probably going to have a rough time doing anything. If they decide to get agressive and have stuff to show from all three markets, then it can come back and remain a stable, and great platform for games.
They need to show games, and that third parties are interested in bringing major games to it in the long term, and they do need at least a slight price drop. If they can atleast price the wi-fi model at $199 and include a memory card then I think that will make a big difference in the Vita being competative on a price scale.
