I wont be pre-ordering, but I will be watching and setting money aside for both. The only FPS games I've cared for was Wolenstein 3d, Doom 2 and BF3. (However BF3's campaign was woefully short and I refuse to buy pieces of a game, aka DLC) I will wait for more info on this Wolf game and am kind of excited to see what Doom 4 ends up being. They have a chance to really knock it out of the park, but if they break it into 20 pieces and the first part 60 bucks, I will be skipping it. Which is why I will never buy another Battlefield game again, BF3 was my first of the series and my last.
Hopefully Doom 4 won't turn out to be a piece of over-hyped shovelware like Duke Nuke Em. I can't recall a game that took so long to make it to launch that was actually good. Also, I still want my $7 back that I spent on Rage. So boring, I couldn't get half way through the tedious campaign.
