Yep it matters so much so(consumer purchase price), that Xbox is getting one whole exclusive this year. Nintendo on the other hand, is obviously cheaper TO DEVELOP for, and considering its sales success due to CONSUMER PURCHASE PRICE, is getting a lot of attention(at least right now).
I'd be more apt to say they are concerned with installed userbase, and while consumer purchase price does somewhat affect that, its not something devs care about directly
(more indirectly if you ask me)
Namco Bandai plans to release only 23 titles for PS3 in the current fiscal year, compared to 24 games to be sold to Microsoft Corp's Xbox360 and 37 titles to be released for Nintendo Co Ltd's Wii console.
