I seriously doubt it. The VAs will be inside of a room talking to fans. The people reporting the event will probably be walking around in the main lobby talking to people who are walking around, not going into a room to watch a Pokemon discussion.
They may be delayed because of the set release and they have to give time to play D/P and if released at the same time everyone will be rushed and they will not have time to get the cards.
Oh while I was gone I gotanother shiny pidgey and about 40 PP UP'S and 3 pokemon done. Feel free to move it because I have not been here for a week so I am posting it here because I want everyone to know what I was doing while I was gone and I got 12 of them in one day a couple of days ago.
reagrding the d/pearl set, i think it will be released a while after the games come out since ppl will be focused on the video games around that time (no big poketourneys til cities).
