As they didn't go last year, do you think they'll go this time? Correct me if I'm wrong, but didn't someone on the cast say at some point that they wanted to go every two years? In any case, I want them to go; the TGS bombcasts are among my top favorites! Also, I'm sure a lot of great games will be on display, not to mention the possible announcement of the PSP2.

that would be really nice.

It would be nice, but they've just moved into new offices, and I think they justified last year why it wasn't worth going to the point where I feel that it just doesn't bang for the buck. Yeah, you'll get some goofy videos, but most of the games you'd see over there will probably just be incrementally advanced versions of CES games.
 
Edit: As for a PSP2 anouncement, it would be worth it if they were able to get hands on with it while they were there. However, my gut reaction is that predicting when Sony are going to release anything is pretty much a black art.
