I really don't care where GE or PSO goes, both are mediocre games IMO. If you're asking me if I were a business man for either company where I would put my game, I would go where the money is, be it from the console makers or from the public. Everything else being equal I would go where my audience is. A large userbase does not necessarily mean more money in my pocket. GE2, much like MH3, would probably make more sense as a PSP/PSV release last year to try and get the audience to upgrade to the new hardware while still selling to them. Not sure that would work right now as the psv is pretty dead and psp is a 9 year old platform. I don't have all the information they do have and maybe GE will sell better without having to compete with MH. I will say that if there was no incentives from Sony and if I wasn't sure where my audience was, I would go with the 3DS.
PSO2, much like DQX, should be on PC first and foremost, after that on a console with a good online framework, i.e. the PS3 or the 360. PSV kinda works because it also does have a decent online framework, though it wouldn't be my first choice.
