Don't be naughty!  As FPS they are clearly competing for the same demographic as you no doubt know.  The mass of PS3 owners who didn't buy KZ3 are just as likely to be the demographic who have zero interest in FPS and only buy RPGs or GT or whatever.

KZ3 cannablized Bulletstorm, it was always going to and I just don't understand what EA/Epic were thinking with that move (no pun intended).

For Bulletstorm to do better on PS3 it either needed a lot of PS3 FPS players to pony up for two full price titles at the same time in the same genre (which was always asking too much IMHO) or chose the new IP that's multiplatform from a developer generaly viewed as MS centric who made some comments about messing with Sony exclusives over a proven exclusive FPS franchise that was the butt of the comments (which I also think was always asking too much even if the developer was actually the People can Fly folks and not the traditional Epic crew).

In short, EA/Epic blew the launch on PS3.  Shame really, it's a fun little title judging by the demo and I did rather like Painkiller back in the day.

Hmm I see where you are going with this, there are exceptions to the rule but yes I agree, this gen has gone wayyyyy long enough for customers to make decisions. Hardcore for mine that arent ps3 excl go on 360, platforms etc on ps3. Kinect... I have no choice haha

they are totally and utterly different style. Bulletstorm is almost a new way of doing fps' while Killzone 3 is the old standard story line etc w/ purrrdy graphics

I do prefer this as well.  It keeps the popularity of a game on a steady trend.  Also, I see it as less hype and more substance when a game has strong steady sales.  It's selling well because people are discovering it as a quality game, not because of hype and bandwagon jumping.

But several here have compared Forza to Gran Turismo which are two different style racing games so whatever.

But I wasn't... How does two wrongs make a right? GT5 and Forza are compared because they are exclusives to each console. (360 and PS3)

I never said two wrongs made a right, and I never said they were wrong to begin with.  Because it's also possible that some shooter fans likes a variety of shooters.  Therefore with wouldn't matter to them if the playing style is very different, so they would just go with the game that they prefer first.

Doesn't matter - they're shooters.  Someone who doesn't like shooters and plays jRPGs etc isn't going to show interest in Bulletstorm.  They're different types of shooters for sure, but it's pretty obvious that they're going to either appeal (or not) to roughly the same demographic.

Also, my point is Bulletorm didn't get the message across it was different in the marketing I saw.  For the average PS3 FPS playing gamer looking at titles in a store he'd (or she'd) see two FPS except one they'd know and one they wouldn't.

We're talking differences within a common genre here, not totally different genres.  An example would be releasing a fun racing title same week as GT.  Totally different style but I guarantee the same result - the less known title will get cannabilized to hell by the bigger IP.

Reasonable start for Bulletstorm on 360, could have been better but not too shabby. In terms of hardware PS3 got a substantial boost from KZ3 launch it seems. Interesting if somewhat mundane week.

Why were you talking about racers when the conversation was about shooters. Lets ignore that, I doubt we will get far with that. 

Really? Ok I would rather most shooters over COD because I like games with substance, am I the majority, probably not, so its nots not tafe to assume anything which is what you are doing with shooter fans preferring both?
