ToyGuru recently stated this in the ask Matty forum:

Put it this way, we have at least 2 vintage toy POP and at least 2 vintage toy NA figures planned for 2013 (including Netossa). Octavia or anyone Filmation that is also POP would be on top of that. Nuff said.
Do you suppose he means only one additional POP character or 2 more in addition to Netossa for 2013?
