Yeah, Nintendo's showing last year was a complete joke. But then again, E3 08 was kind of bad all around. I think this year will much better for everyone. Microsoft is promising big new announcements. Nintendo and Sony both have a number of exciting games that have been in the oven for a while. As for Nintendo, correct me if I'm wrong, but the only big "gamer's game" they've released this generation is Super Mario Galaxy. So I'm positive that they'll be showing some stuff they've been sitting on for a while that even I can get excited about. (Hopefully.)
I'm 100% positive we'll see Nintendo ******ing themselves for the first 30 minutes or so, but that will probably be true for all the press conferences. I think they'll finally show Zelda Wii, which has been in development forever. Remember, they casually announced this game before Twilight Princess was finished and before the Wii was even announced! I doubt we'll see Kid Icarus. As far as I can remember, Nintendo hasn't really shown much interest in that series. I'm pretty sure we'll see Pikmin 3 and maybe a new Kirby. It would be great to see a new Star Fox game, but that's not going to happen.
