"2010 is going to be a worse year for free-to-play than 2009 -- the novelty will have worn off, and I suspect fewer people will be investing in some of the item malls. Microtransactions aren't going anywhere, though, and the DDO model might get picked up a couple other times. "

I'm not sure that the way you pay for a game is all that important. If the game is crummy (or entertaining) it hardly matters if it's P2P or F2P. It will stand or fall on its merits as long as it generates revenue.

And the DDO model is very likely to be picked up by other companies if it turns out to actually be profitable. I wouldn't be surprised if another major IP goes this way in 2010.

And on the F2P front, Allods Online is still in Closed Beta, but it should do quite well, assuming they don't go nuts with the cash shop or completely blow what appears to be a very ambitious endgame.
