Woot thanks OP! Canceled my preorder with gamestop and preordered with amazon. Unlike a lot of fans I loved Dead Space 2 just as much as the original (even the iPad game was fantastic) so I can't wait to play DS3.
Its just a shame that the pc releases were such a mess between DS2 missing DLC and DS3 not being on steam (thanks origin) this will have to be a PS3 title for me. I'll pick up the PC version later when its on sale really cheap.
