Multiplatform almost definitely, exclusive probably not.
You saw squares yearly financials, they lost 150 million dollars this year. They are gonna be doing their money making bargain bin crap this year.
The person who thinks they would pick 360 over cafe is just clueless. Square is an old fashioned jap company and they hate making titles for non-japanese consoles. They almost made FF13 a multiplatform for the Wii, but couldn't justify it. Now that the Nintendo is gonna be in the same league of power as the PS3, theres a better chance that Square will drop the 360 altogether in favor of nintendo and sony. Although I think at this point they will bear with it.
My friend told me a story once about asian loyalty. He goes to this car repair shop in a Richmond BC Canada which is the heart of Canada's asian crowd. This place gets a AA ranking on BBB. It's used by the government, FBI, RCMP, etc for all of their cars because its such a great business. He told my friend that he can't get an asian customer in his store for the life of him. Asians are stupidly loyal to asian brands.
I think they have a better chance of getting a Kingdom Hearts title as an exclusive but given Squares losses they will probably multiplatform it.
