I mean sure there will be some crossover, but I really doubt the bulk of those buyers bought it on PS2 if they had access to PS3 considering it looked better and had more options.
That is unless there was a big mark up on the PS3 version compared to the PS2 then I could see it.
Well, a few things to note in this particular scenario:
Gundam Musou 1 came out on PS2 a year after the PS3 version (PS3 = March 2007, PS2 = Feb 2008) and actually had more features and stuff. The PS3 market two years ago was also not as healthy as it is today, so I would imagine most of those users didn't have a PS3 at the time, yes.
Gundam Musou 2 came out in Dec 2008 (the same year as GM1 PS2) on all 3 platforms at the same time. It can be reasoned that most of the people who bought GM2 on PS2 are the same people who bought GM1 on the PS2 in the same year. It was 10 bucks cheaper than the PS3 version, but I doubt that was the main reason it sold well on the PS2 too. Most of these users probably still didn't have a PS3, as it was only 10 months later.
Gundam Musou 3 is coming out some time between Dec 2010 and March 2011. This is a good 2 years after GM2. Do the majority of PS2 users who bought GM1 and GM2 have a PS3 by now? We don't know. Will there almost certainly be a percentage of them who have moved to PS3 by now given the release of the Slim, FFXIII, and various other PS3 franchises doing much better now? Yes, without a doubt. Do the people who bought GM2 even want to get a GM3? Also unknown at this point.
That's basically how I see it. There could be a LOT more crossover this time, and a comparison with Sengoku Basara 3 is not quite valid, since the Wii and PS3 are both existing systems competing now, while PS2 users from 2 years ago could well have upgraded to a PS3 by now.
