On Amazon's Mover's and Shakers list Vita games see huge increases in sales. This is most likely because of the Buy 2, Get 1 Free sale on Amazon.

Things are looking really good for Vita on Amazon. 

HOORAY!! Hope it keeps up!

This won't reflect too much in total weekly sales imo.

Theres 1 less baby seal on the planet.

I'll probably pick up Rayman Origins for the Vita when it lowers in price. It feels more like a handheld game to me.

I really want Rayman Origins and Lumines, but 40 bucks for each is a little steep considering the games they are. This 2 for 1 deal is just what was needed.

I want to see more RPG's then I might jump in.

amazon is one of many retailers though, i don't really think that this can be generalised to how the vita is doing as a whole
i really do hope its doing well though

according to amazon mass effect 3 is top seller

Happy to see rayman origins at #2.
