Did I miss the news that girls don't own Xboxes, or that a large portion of the people buying Heavy Rain were female?

Wow.  You just proved my point and probably didn't even realize you were doing it.  Wow.

i hope their next game is for the 360 and ps3, more ppl need to experience their style of game design.  :)

I don't think there's a gaming system on the market that has a higher percentage of male owners than the 360. I don't know the ratio but I wouldn't be suprsised if 80 to 90% of 360 owners are male.
I didn't say a large portion of the people buying HR were female. I'm saying that imo many women would love HR (and I bet some already do). Many women love the broad genre of graphic adventure games (incl. all subgenres from classic p&c games to Prof. Layton puzzle style to the modern browser "casual" adventures to interactive movies - see also The Sims franchise which imo and fortunately is not a mere boring life sim anymore but an adventure game in soap opera style). MANY women love crime and thriller stories and games based on them (e.g. CSI games sell quite good on all systems), that's why I think many women would be interested in HR or a similar successor if it would run on their PCs/laptops. Plus: The mainstream thriller story of David Cage's last game would cater even more to the female audience than to the male. And where are the largest female gamer audiences these days? Clearly on PC (and on DS/Wii).

Um I didnt say that, All Im saying is Why cut out other potential buyers?

Remember Quantic Dreams isnt a first party company and yes Sony has helped them out alot but thy are an "independent company" and if maximizing profits is by going multi, then by all means they should

Besides If I was a developer I'd want as many people as possible try out my awesome games too

Why go out on your own when you have a steady stream of cash, great support from a publisher and a very happy fanbase because of that publisher? You don't even have to worry about money once your making a good game, SONY does.

SuckerPunch has things right.

They were busy supporting Gabe Newell

To people who are saying heavy rain would have been a bigger success on xbox 360 are wrong. Sure xbox 360 may have the highest attach ratio but a game like heavy rain just wouldn't sell well on a userbase who loves shooters. A great example would be alan wake. Alan wake was a story driven game that would have actually sold very well on ps3, well because ps3 owners love story based games. Im not saying alan wake sales were that bad on xbox 360 but it just proves that the 360 doesn't have a strong userbase for story driven games like heavy rain. Also there is a something about games published by sony that just makes you know the game will have quality. There is always somethign in sony games. When you play the game the 1st time you know that sony published the game. 

Time will tell, but I think there are publishers out there who can provide QD the ressources it needs to shine. One of those are of course Sony, but being with Sony limits the potential audience.

I understand why anyone would be sceptical of this, David Cage too, but if they want to expand their market, then something needs to happen.

Hmm it's an interesting gamble.

Look at Heavensly Sword guys - HS was quite succesfull with sales and reviews as well as gamers opinions but they chosen to develop new multiplatform IP now they have game which has absolutly no hype and almost noone talks about it.

It will be interesting to see but i think Enslaved will strugle to reach number of pieces HS sold.

Same can happen to Heavy Rain guys- once everything is said and done it might burn them instead of bringing big profits. Compared to that doing another game with Sony this time with move support built in from start would be safe bet into how many sales they can get
