Personally I think that they should work on some more DLC. It couldn't be that hard to make updates to add more tricks into the game, an option to buy more levels or open up new sections of the map or even make new multiplayer modes- a free roam split-screen would suit me just fine.
(This was a bugger to get a hold of, as the official UK site for SKATE still hasn't been updated, and the American one just re-directs you back to the UK...)
But all this said, I will probably buy this title straight off. As much as I'd prefer DLC, there are some major flaws on Skate 2 that could be fixed or improved- namely the crappy physics when you're off your board...
