There's a pretty big thread on the Sony boards about the F2P stuff. Anybody that has an account and has ever paid will automatically get a silver membership. It's the 100% new accounts that will be on the free list. Also, any character that has existed will be grandfathered into playable. So if somebody wants to play their level 75 gnome enchanter will be able to do so even though it isn't on the race/class list for silver. This is why my wife's accounts with a halfling cleric, wood elf druid, iksar shaman, gnome chanter and gnome rogue will make an appearance once in awhile.
