If a company came up to me and said "We have interest in reviving an IP of yours. We will take on the development costs, we will take on all the risk, all you have to do is say yes and you will get a fixed percentage of every sale"--that seems like an easy win-win, does it not? The only reasons I would imagine you would say NO were if:
1) Concern that the company will do a crappy job and tarnish the brand's reputation (which, fair, but Nightreign studios and/or GOG seem to have a pretty solid track record on this)
2) Your company's bean-counters are both so greedy and risk-averse such that their thinking is, "We only wish to allow something if it will be a guaranteed hit...but if it is a guaranteed hit, we want to do it internally so that we get to keep all of the profits!" In which case, the requirements are almost impossible to satisfy, since there is inevitably some level of risk undertaken during the remaster/re-release effort.
