Thankfully, assuming CvS2 ever gets such a port, “arrange” modes are unlikely to happen simply because Capcom will probably look at the sales projections and determine such a retuning to not be worth the additional expense.
I say “thankfully” because moreso than many other games (except Marvel), CvS2 has so many matchups to rebalance (less characters than Marvel but effectively a lot more matchups due to the various grooves) that trying to retune everyone in the cast to have condensed tiers without the aid of roll cancel (which they would presumably remove if they were going to go that far) would probably end in disaster for certain characters.
This game still needs a port so bad, though…even a bare-bones one with no netplay would do so much to bring the Deuce back in areas where it’s fallen off due to SSF4. Part of it is brain drain from so many people having burned out on CvS2 back in the day, but another big factor is there’s a lot less leeway to bring in promising upstarts from Super 4 and the like because netplay is no longer a factor (sure, it’s netplay, but it’s SOME kind of grinding zone for novice players who can’t find competition) and you basically have to build your own PS2 stick these days.
Despite its reputation as a prohibitive game to get into (this is a VAST oversimplification IMO…how much work CvS2 takes to pick up depends largely on who/what groove you want to play…my team is a prime example of extremely low-hanging strategy and execution fruit), I think just having the Deuce on current-gen consoles alone would do a lot to bring it back into the public eye.
It would bring in limited new blood, to be sure, but it might also help bring back some of the old blood who acknowledge SSF4 as a dumber version of CvS2 and had previously hemmed and hawed about getting back into the game due to no PS2 peripherals/console or whatever. For better or for worse, there’d be no more excuse.
Get on this shit, Capcom. We KNOW that groove is in your heart.
