Generally speaking, PoE is a terrible topology for lighting. It would be moving a basis of system design from daisy chaining fixtures to a home-run-per-fixture cabling scheme. There are also problems with melting cables when you bundle lots of PoE cables together that this last cycle of the NEC has begun to address -- the kind of bundling you might see out to a lighting batten. It's not bad for decor lighting and certain architectural products but it doesn't scale up well to the be the principle form of lighting for a theater.
I think we're more likely to see a homogenized cable standard with power and data that falls somewhere between today's scroller cables and Lex's new hybrid PowerCon/DMX cables. Preferably with a sister standard that allows pass-through power with built-in per fixture power relays so we can stop dropping these large DMX relay panels into every project that serve little purpose beyond extending fixture longevity because manufacturers don't care to figure this out.
Whether that standard incorporates DMX, sACN, honest ACN, or whatever leapfrogs ACN for taking so long to come to market is up to probably ESTA and three hundred manufacturers to argue about before having mixed success bringing it to market.
