They are, I just bought 2 of them ( one is an xmas present).
Also went to Best Buy and had them price match 2 DJ Hero bundles, tony hawk and a regular guitar hero bundle too (TRU was all out). The best thing is that in the middle of those purchases, I got a $10 reward zone card, so one of them was technically free.
All paid for with my 3DS refund. Thanx Nintendo!
