Something TG posted many pages into this thread and which will probably get missed by a great many people as a result:
1) It's not going to be for a while if the green light's just been given. Think 2012, not 2011.
2) It's unlikely it'll be with a 200X-Skeletor - as things stand, that would be still be a standard MotUC Skeletor with a white skull & Keldor's cape, which wouldn't be worth it - and they aren't going to redo Keldor.
3) So, logically, it'll either come with (a) whatever Skeletor variant they were already planning on next [post-BASk, that is] or (b) with an unrelated character as a "secret accessory", ala the 200X He-Man sword's inclusion with Man-at-Arms.
Anyone disagree with my points?
