Ah, I gotya. Although, I don't think Hasbro would want to combine two different versions of the helmets. Or, even if they did, I'd imagine diehard fans of Vader's costume and others would skin Hasbro alive for doing it.

Oh my god, is there any chance at all of this wondrous thing occurring? Would it be greedy to hope to see her in a two pack with Velocity. :D

One of the upcoming Titans Return boxsets (the replacement for Combiner Wars' box sets) is rumored to have her in it.

Maybe. As Jeddostotle7 says, there is a rumour. Last year someone sid there was going to be a titans Return box set ith Nautica in it (retooled from Blurr, and recently a box set with that name appeared in teh computer systems of some American retailer or other. But we don't know for certain it will have Nautica in it.
I'd kill for Velocity as well, I love her design.

Nautica confirmed, not sure if I'm allowed to link to pictures from social media for TF coverage though?

So out of fifty entrants of my collective top ten wish lists, I’ve been right about a whopping three (Jawa, movie Nebula, comics Sif)!
More Toy Fair thoughts in my signature because I'm wordy.
