Not gonna happen for the simple fact that the developer favors Sony consoles. There has yet to be a Katamari game outside of the PS2/PSP/PS3.
Final Fantasy 5 and 6 on the 3DS might happen. I'd love to see 6 make its way so I can enjoy Kefka all over again <3 Kefka > Sephiroth I would love a Majora's Mask remake, its my most favorite video game of all time period. And the best Zelda in my opinion. But just watch OOT will have its remake but not Majora D= Bull if that happens.. With Super Smash Bros. For the 3DS coming that pretty much sold the 3DS for me. I'm still going to wait for a price cut though, I'd rather pay 250 for a vita then a 3DS at the moment. Now just give me my 6th generation of pokemon and lets call it a system already.
I enjoyed Katamari the first couple times. Then it just go so fucking boring, the Japanese weirdness couldn't keep it up for me. And people complain about CoD being the same.
A remake Of FFXII (PS2) on 3DS is my ultimate Dream, Then There's Golden Sun 3DS; And of course Pokemon 3DS
Pokemon 3ds is pretty inevitable I would like it if they made Elder Scrolls 3DS. Bethesda and TES aren't tied to Microsoft or Sony so it's a possibility
I'd like to see a 5th addition to the Phoenix Wright/Apollo Justice series. There were just too many unanswered question left by Apollo Justice. Perhaps a new console would be a good incentive for Capcom.
While not really a part of the Ace Attorney series, there's that Wright VS. Layton crossover that's due in 2012 http://www.youtube.com/watch?v=HAN7qiE9FVE
tales of vesperia tales of innocence tales of heatrs seeing as innocence and hearts didnt get a english release maybe a revamp of them on the 3ds would be a awesome sales boost tales of phantasia 2 3d
At this moment, I wish to have a working 3DS again. It fell out of my hands(my bro's fault) and now it give a error after you boot it. So my 3DS is on it's way to Nintendo for a repair...
Some Level-5 RPG remakes (and, ideally, some new games from them). Also, I'd like to see a second analogue nub on the 3DS, but that won't happen because Nintendo are idiots.
