Legacy Members: $9.99 for 40 characters - 8 per world.
Basic: $12.99 for I believe it's 8 characters - 1 per world (Don't quote me here, but I know it's $12.99).
Premium: $14.99 for 40 characters - 8 per world.
PC version will retail for $29.99 (however all existing and previous PC owners will obtain a FREE upgrade to the new client. So you will not have to pay anything, and you will receive another 30 days free trial). PS3 will retail for $39.99.
