Methinks Cave is a connoisseur developer with a delicate revenue stream. Seems they use the principle of scarcity to really ratchet up the fanfare in the few products they do produce. Given that, if there was a such a device to make their IP's plentiful, I'd imagine that takes away from their scarcity marketing schemes. They'd throw everything they got to knock that down.
Sega, Taito, Capcom, probably have deeper pockets and understand the effort to knock that down isn't worth the resources they'd have to put into it. Like that line from Fight Club:
"A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one."
I think X for Cave will always be more.
