Time to scalp the leftover Armada Megs at Target and ToysRUs, and sell them at a premium in 10 years time.. Just kidding! Please don't do that!.. Even if you do, there's a chance Hasbro will come up with an even better Armada Megs by then.
Even to non-G1 fans, I think Sixshot will be a hit, especially if they can get him before Christmas. He has 6 modes AND he's got a cool little pilot that makes up his head!
I think with Titans Return toys being on sale so often this year (even without a sale, the TR deluxes were still cheaper than the RiD warriors), plus with the added play value of Titan Masters; I think the line has attracted new fans that probably weren't into G1 to begin with. I don't think Combiner Wars sold this well last year.
