More new figures in spring?

[Triceraton]

Diamond Previews that came out today has a full page ad for the TMNT figures, and it says "18 New Figures for Spring 2005". I'm assuming 4 of those will be more TMNT variants, and 6 of them we already know. That would leave 8 more new figures just in spring that we don't know about.
(note that they're not talking about the Air Ninja figures or any other deluxe figures, they're listed separately).

There's also a write up for the Air Ninja figures:

Come fly TMNT-style with these articulated 5" figures with several different features. One-touch-action raises each figure's arms ready to "fly." Each figure's removable backpack has one-touch-action that ejects wings. The included levitation platform can be used as a stand to pose your figure, or one-touch action to simulate flying on an automatic string. This assortment is scheduled to include Air Ninja Leonardo, Donatello, Raphael, and Michelangelo, plus Air Ninja Shredder & Foot Soldier. Each figure includes rocket boosters, helmet, and accessory rockets.
