Will this year's E3 be a big one for gamers?
Bigger than last year? Maybe, bigger than Next Year? Doubtful. The best of the best E3's introduce new consoles. So unless one shows up I don't expect it to be mind blowing.
Which system will have the biggest showing? Which one(s) will look pale in comparison?
They all have somthing big coming... fans of each console shall be happy. But personally I say Xbox or Ps2. GCN got no Sega sports, and the big three games I look for aren't going to be there (Mario, Zelda, and *cough* the next Rare FPS
)
Which development team will wow us the most?
Nintendo or EA will most likely have the most blockbuster announcements. As far as finished games I dunno.
Will you fall under the spell of the media?
Most likely
