I believe that the theory of the shooter genre being crowded is just silly. Hell, holiday season 2007 had dozens of shooters (Halo 3, Call of Duty, Blacksite, Timeshift, Stranglehold, just to name a few), and that didn't stop the success of AT LEAST the first two. The others were generally flops, mainly for being average or mediocre games. Having lots of high profile shooters will only make the genre more popular. And isn't Fallout an RPG? I'm not a huge fan of the series so count me confused.
You could also argue that Motorstorm will face competition from Need for Speed and Midnight Club as well. Just remember that back at the time, Motorstorm was considered the second decent exclusive game for the PS3 (it had a launch of 100k in the Americas, which was considered a milestone for the PS3 back then). Without the bundles, I just couldn't see Motorstorm hitting the mark.
