This would be a colour version that Hasbro wouldn't likely do a general release of to stores... and FunPub won't be doing it as a Club exclusive now, or else it would upset those in the customising class.
So for anyone wanting a Gen2 Sideswipe figure in the Classics/Universe line, your chances are now very slim.

With only about a hundred of these things being handmade by convention attendees (almost all will keep it), this figure will be in demand on the secondary market.
