G.I. Joe Sigma 6 Toys

Were any of the Sigma 6 toys released down here? We definitely got the last few Spy Troops and some Valor Vs. Venom packs, but I don't remember ever seeing the latter toyline in stores (Toys R Us or otherwise).

If not, then it's a shame because that R.O.C.C. looks amazing.

I think I did see Sigma 6 in my local TRU for a short while but I don't think it was very popular.
I did like the anime for it though. :)
