KZ2 has great detail, but I don't like the "bluish-grey" theme. R2 has more realistic coloring...
Both look great, but I noticed that KZ2 has been moved to Februray 2009 on Gamestop's web site in the US. It was listed as September 2008 before this week. So, its really a non-factor this year.
R2 looks great but I want to see the campaign vs. the multiplayer.
