Rumor of the Canon 5D M2

I've heard rumor of an up coming version of the Canon 5D. Here's the link to the article.

Here is a list of what it is boasting.

21.1 MP 1.0x
DIGIC IV
ISO 100-6400 L:50 & H:12800
5 FPS
3.2" High Resolution Screen (LCD)
19 point AF
HDMI Out
Liveview
HD Movie Mode
Viewfinder: 100% Coverage
Full weather sealing
EF Lenses only

I must admit, I've never used the 5D so I'm not sure what it's like compared to the crop sensor models. Perhaps I'll have to get my hands on one and review it.
