Well I'm definitely getting it for the PC. One of the advantages PC has over consoles are mods that can extend a game's life and replay value. Playing new campaigns or missions after I get tired of the original content will be nice.
Completely true for most games where single player is the main purpose of the game. For example the playability of Fallout 3 was a lot better if you had it on PC because of all the expansions and user created content that was out there.
But, and this is one of the big reasons people use XBL, people like to feel connected to other people, that they're not alone and even if they're not playing a multiplayer game, they can still be experiencing things with their friends at the same time.
I'm not saying one is better than the other, just giving some perspective. People should play on what they want to and enjoy themselves while doing so otherwise what's the point.
