Well, I know Swaffy collects them but in case someone else does too I'll post rather than e-mail.
I went to TRU yesterday for the first time in quite a while just to look around. As I was leaving I walked through the diecast section and happened to notice atchbox Collectibles planes. They are the same size as the Battle Squads planes and look really nice. They don't come with figures and apparently have no action features so they're pretty much like the upcoming AFs They all come with stands too.
There are 6 in the series, all of which seem to be easy to find. I got 5 yesterday and the 6th today at another TRU.
The six are:
They are 13.99 each (14.69 with tax around here)
I hope they come out with more, I'm surprised there are no Axis planes in the series.
