That would still cost money to renew the contract, money that would be better spent on MvC4.
Here's the problem with your plan.
Nobody's around to make it.
Nitsuma's dropped off the face of the planet.
Eighting's nowhere to be seen.
There's nobody for Capcom to farm this out to.
On top of that, renewing the contract doesn't have to be a one or the other. Write the contract to renew the licenses on the delisted games and get MvC4 in there too. How do you think MvC3 came to be? That digital version of MvC2 wasn't some random event.
By the by, you're not getting a band-aid for UMvC3 for the same reason there won't be a MvC4 in the near future. You're stuck with what you got. A Hulk was on the winning team in EVO, your game's fine.
I'd appreciate them getting all the various Versus games and their DLC back on digital storefronts and patching back in Swagneto because I guess the Spanish government can't hold a grudge forever.
In other news, getting the DLC for both UA games would be nice so you don't get played on eBay for a copy of Gold Edition. Same for that Deadpool DLC and whatever else got delisted along the way.
