Splinter Cell Conviction not Microsoft exclusive, after all?

After looking around a bit on Gamestop.com in search of a few good deals, I decided to see if they had any copies of Splinter Cell: Essentials for the PSP, but alas, I found something better. The often gloated about Splinter Cell Conviction (coming this year for PC and Xbox 360) is not just Microsoft exclusive anymore. There is a Nintendo DS version coming out, as listed on Gamestop.

The DS version will doubtlessly suck, so I don't think Microsoft has to worry about losing 360 version sales, to the DS version.
