Epic Slash writes: E3 is basically the Superbowl of gaming and leads the way for most of the announcements for the year. However as usual there are a number of games that were curiously missing from press conferences and reveals. Games that seem in danger of becoming vaporware.
The Last Guardian and Final Fantasy Versus 13 have a much better chance of appearing at the Tokyo Game Show and we should expect that to be the case.
As for the rest, well they're either relatively new announcements or the devs feel (as in the case of Bioshock and Zelda) that they've built enough of a hype train to miss E3 and keep going.
