An anonymous contributor managed to find this Retaliator at a local Toys R Us in Duluth, GA. Right now the "Buy one Get one 50% off" Sale is still going on too, so this fan really lucked out! I've checked my local stores and haven't found any Elite Products accidentally stocked early like this lucky fan, but it's not uncommon for slip-ups like this to happen before the actual release.
For now I guess I'll have to keep using my Elite Longshot to hold me over. With some folks reporting that the 75ft flat ranges aren't quite true, I'm kind of excited to see how my LS matches up to them. That, and I'm itching to see if these Blue Darts have solved the problems streamlines have.
