At this rate, there are probably only a few occasions to really be concerned about legal action… or during/after an official release of the OOT (if they feel the DeEd could harm sales of a product they’re finally trying to sell).
I love Harmy’s versions. But man, they’d have to really butcher their own release in order to make that a valid concern. Still, they may find a way to manage.
You never know what greedy people will do. There’s already people trying to sell it for a profit as it is, but they could try to pass it off as an early release of the official version or something silly closer to the release date… Product confusion is not looked pleasantly upon. Granted, at that point, they’d probably have better results coming down on those sellers, than messing with Harmy. After that, if Disney screws up an OOT in enough ways that could use the Harmy touch to make it more authentic (using the new official source), then things could get really interesting…
