I'm in, as a pre order / 6 months sub CO member.
All I can say form experience of CO is to stay away from pre ordering or buying any limited time subscriptions.
Check out the Beta. Then wait for a couple months after release before laying down any money.
They bait-and-switched us who were playing Champions Online.
They gave us a great fun beta, then switched the game on release day to a completely different feeling game. A game where superman gets beat up by three thugs with bats. No kid: you can play a super strength / super constitution might character with invulnerability and get your face smashed in by normal guys of the henchman variety.
Go take a good look at their forums: its a bombshell even now. Though most of us said our piece and packed up and left, leaving the sycophants behind.
That company is not to be trusted. To be honest, I smell Roper's hand. It won't be long before your Bat'leth wielding Klingon warrior is getting beat up by a couple redshirts kids with their fists.
Can't you tell i'm bitter over CO? heh.
