This is pretty surprising when I first read about it, but now it is happening. Former UFC Heavyweight Champion Brock Lesnar returns to what made him the beast it is today. He is a playable legend in WWE' 12, which is out next month. Considering what you have to go through is get this approved from the UFC, this is pretty big. Dana White has said on numerous occasions that him and Vince McMahon are good friends and not competitors, so I guess Dana decided to let Brock appear in a wrestling game again. Of course, it doesn't mean The Next Big Thing will return to the actual WWE as he has a big fight against Overeem in December for the UFC, but its still nice to see him back in a WWE product.
Here Comes the Pain indeed (I'm not sure about his remixed entrance music as the original is still pretty good)
