Hehe, I'm an RB6 fan at heart as well, had the original and played it for hours... still remember all the maps too (Embassy.. Hutu Rebel Camp, Electric Dam, Hacienda...), I remember having dreams about Rogue Spear too. Those were the days.
Just had a debrief on this year's Tokyo Game Show as well. Lost Planet and Project Slypheed look amazing (both for the 360).
