Wow. Perhaps there will be a big E3 reveal and not just the "working on it" line.
It has to be. The thing is being released in March, less than a year away and this is the event the press actually pays attention to. All the cards will be on the table.
I personally think it will have a good launch lineup. After Nintendo's domination everywhere and especially with the DS they have to want to get in on the ground floor here. Also Nintendo knows they can't count on them to release something so they will have something good.
This time Nintendo doesn't have to push things out faster because of the psp and there won't be some big stigma about them getting pushed out of the handheld space, they have all the expectations on their side and that will give them a much stronger starting lineup.
