So they're mad that Sony decided to bring new IPs in, instead of rehashing old franchises over and over? Must be a Nintendo fanboy

I'd love for Sony to establish a franchise with amazingly fun and addictive multiplayer gameplay such as Smash Brothers or Mario Kart...the two franchises never get old! If the customer base is eating it up, why stop accomodating the demand?

Even Microsoft has its Halo, but I'm no fan of Halo.

the problem isn't that sequels are selling bad, it's that Sony isn't taking good enough care of their IPs. They've never been good at it, making far too many sequels far too close to each other.

How has Sony not taken care of their IP's?

All established franchises were original IPs in the beginning.

Yes, Sony needs to put some time to build an IP.. they change IP just too quickly before it build momentum

First there's complaint about the price, fair enough, then they complain about there being no games, ok 2007 , then they complain about too many sequels, ok a lot 4 and 5 in too many games, now it's because the ps3 has too may new ips. That's when i say, you complain too much.
The PS3 is in third and will stay in third, their games don't do as well in NA for some reason. Sony is stuck, no matter what they do, any strategy they try, it will be seen as a failure because its best days are behind them. We just have to deal with it.

Well, US sales are not a proxy for the world market of gaming. The PS3 is a high-end media device, which means it is not going to match its lower-cost competitors in terms of software unit sales until it hits that magic $299/299EUR price point. When that happens, we'll have a fairer comparison.

Investing in IP is much more complicated, though, than simply paying a studio to create stuff. One Sony does very, very well, but receives almost no credit for, is strategic depth: its game division understands that videogames are tightly connected with all the other media (film, TV, music, theater, performance, animation, you name it). As such, they have to give back to the media forms they borrow from, and be willing to learn from other media.

Insomniac didn't just create another shooter with Resistance, they created an entire game-world, along with characters worth caring about, back stories, video clips, comic books, etc. That's a model for all developers and other media artists to aspire to.

A high end multimedia device which doesn't come with a remote standard?

Also if you consider the sales leap spaced one year apart for the major price cut event, even a price cut would only lift sales by aprox 25% or less year over year without other supporting factors if the impact is relatively the same as the first price cut.

Sony hasn't really shown much success in creating a world around their I.P so of course they won't get lauded for it. Halo has something like 6 novels and a graphic novel and a comic series and at least one major online show in Red vs Blue. If they finally have some success they will get credited for it. Gears of War has a comic series and a book and a movie coming and more importantly it has the sales to back up supporting work.

$299/299Eur is not a magic price point.. i think its below 250 that one get to the magic price point... 

Definitely sales will increase at $299/299Euro..
