Just registered to make a little bit of noise like a couple others.. I REALLY want TVPlus to be a reality!
I think that it's fair to say that WMC has always kind of been a niche product, in fact most people don't even know what it is (I've always referred to it as the best Microsoft product nobody's ever heard of), but I think that niche market is still one that is crying out to have someone fill it. While I don't disagree that streaming may be the future, it's likely to be quite a ways off if even possible. Most programming can be streamed, but not live, and even then it's very difficult to be able to watch sports programming unless you've got cable/satellite, unless you don't mind watching a poor quality illegal stream that's riddled with malware and ads. Simply put, the NFL/NBA/NHL/MLBs of the world are quite happy reaping large sums from the telco providers, and unless they get big incentive (eg huge piles of cash), it won't change.
I love my cablecard WMC box, as do others that I've met who use them, but at this point it really is on borrowed time. Sure, we can still keep using Windows 7 for the time being and hold things off, but if Microsoft decides to kill off the EPG then it's game over. Plus, Microsoft just announced that they'll only support the latest generation (and newer) Intel processors with Windows 10. This isn't to say that we can't keep using the PCs we have today, but if we want the features that a new motherboard or processor will offer (onboard HDMI 2.0 via the Intel GPU, for example), then WMC is out of the question. To that end, if I can't use my PC as a DVR, I've got no incentive to have one hooked up to my TV when I can get something low-power like a Roku to do day to day streaming. Sure, I could cook up a JRiver box to support everything but the copy-once programming I watch, but I want everything in one place. Besides that, it's likely only a matter of time till companies like Comcast and TWC decide they're going to flag the whole kit'n'kaboodle as copy-once so they can get more revenue out of their DVRs, and push their whole-home solutions.
Anyway, I'm sure that research has been done on the viability of getting the licensing, but I don't think that the results of the Kickstarter are necessarily indicative of what the TVPlus product would yield. I mentioned it to several co-workers after I put my name in the hat, and while they were very interested in the product, they're not the types who are going to buy into anything unless they can see the final product and get it that day. I want this product badly, and I think a lot of other people will too, it will just take some time for people to see it and then believe in it enough to buy into it.
