I don't think I would be able to handle ngpc titles on the ds. That stick would make me rage. On the 3ds however? Yes. Motm would be mine again.
As much as 'd love so see SvC:MotM re-released on a console with more visibility, SNKP would probably need to work out some licensing deal with Capcom to distribute something with their IPs in it outside of the hardware it was originally released on.
I'd pay good money for that, as it's still the best crossover between both companies, but many people wouldn't be able to look past the small color count to make it profitable.
As much as I love SNK's stuff and am willing to throw money at them, I still want to know if it'll be possible to add more games to this - most of them I already have from older compilations on the PS2, and I draw the line at buying the same game(s) twice.
I don't think 3-Count Bout was in any of them though - it was nice when that game got a nod in KoF XIII's intro dialogue between Kensou and Raiden, through a mention of Red Dragon.
