I'm definitely not alone in still thinking of Devil May Cry and Grand Theft Auto as PlayStation brands. There were obviously a lot of people who picked up the PlayStation 3 with the express intent of purchasing those titles before their multi-platform statuses were revealed. Despite the large install base advantage the 360 has over the PS3, GTA IV on the PS3 has done quite well:
360 - 6.56 million
PS3 - 5.18 million
Sure, the 360 still has a substantial advantage in sales for GTA IV but it doesn't match up, proportionately, to other multi-platform titles.
Devil May Cry 4 on the PS3 has actually outsold the 360 version. I wasn't sure that these figures would stand the test of time but they certainly seem to have:
360 - 1.18 million
PS3 - 1.29 million
These aren't the figures you'd expect from a system that has an install base advantage of ~7.5 million systems and the only explanation I can come up with for it involves some sort of brand loyalty - though in the case of DMC4 at least, it just comes down to the Japanese numbers.
To contrast with the GTA IV numbers, we have Call of Duty 4:
360 - 6.85 million
PS3 - 3.9 million
