I'm really not sure that Lr has any future going by some of the discussion here. Really, if all people are interested is Raw development then the question needs to be asked, what does Lr have over Ps/ACR? Absolutely zip, IMHO. The tools that Aperture, and then Lightroom, bought to the table were intended to provide a single environment within which photos could be managed, catalogued, developed, and edited (how many people here know what "edited" means?). Aperture, with tools like the light table, comprehensive stacking, versioning and organizing, and the book editor provided a fantastic environment for working on a project. To risk the Wrath Of Schewe, I'd say that no pre-release screenshot of "Shadowland" I've ever seen indicated that Adobe had thought of anything even vaguely on those lines, and all the non-Develop Module stuff looked to have been rush built and bolted on in 6 months - and never improved since. But nevertheless, Lr has these tools, and since the competition has self-immolated, they're no longer second rate, and for me, they're mission critical. Slightly better NR at ISO 25,600? Not so much. Capture One, on the other hand, does not offer much beyond Develop - and yet, apparently, people are flocking to it. So, the conclusion must be that the market for the non-Develop stuff is very small, and therefore, the justification for Adobe to support 2 advanced/pro-level Develop-focused suites is very low. Hence, push the advanced crowd back towards Ps, and use the Lightroom brand awareness to create a new / replacement product to compete in the consumer market.
That's one way I could see it going. I hope I'm wrong. But also, having been an Adobe customer for years, long enough even to remember Adobe Fetch, Streamline, Dimensions, etc, I really don't think they are capable of winning in the consumer market. It's just not in the company's DNA - or what's left of it.
