I did talk about conferences in my last post?
E3 and something like PSX works just as well for europeans. Depending what they are ready to show it might be a good idea just to hold the stuff until PSX if it means less events like the god awful TGS conference this year.
There's EGX in the UK but I think European PS fans really deserve an event where they can interact with the developers, watch panels and get a community feel. That is sorely missing from Gamescom; in my opinion you need to be pretty masochistic to go there as non press.
I kind of agree that two Sony events are more than enough per year but PSX really should be a travelling show. Maybe do Europe, US East coast, Europe, US West coast. Or go to Australia once, they deserve some love, too.
