Is Sony having an Windows 8 App Store of their own?

I'm sure one of you guys are going to help me find an explanation for this, I just saw this video of the Sony Vaio Tab 20 (A cool concept BTW) and at minute 2:00 there is what seems to be an alternate desktop app store, can anyone help me understand?
