Personally i hope PFO will do well i just hope it is not like DDO i played it for awhile and i hated how it was nothing like the really dungeons and dragons. Mind you i know not every one is in to that kinda game but if you make a game based around it don't butcher it just try to make the system more interesting.
that being said i do hope it is free to play i have played WOW and such and i hate having to pay 15 bucks a month or 30 every 2 for cards i personally think it is a waste. that is why i am switching to Guild wars 2 and daiblo 3(though daiblo is not so much an mmo lol)
