Win 10 ecosystem is different to console BC. As you say, there might not even be an XB4 because it probably won't be needed. If it exists, it'll just be a Windows box. BC as discussed here is emulating an alien architecture on a new box, or building a new box around the old architecture. Building an abstracted ecosystem is somewhat different - that's more an alternative strategy to the classical console business.
I disagree, and I guess this is where some of our conflict lies. You want to focus just on how BC is impacting the current state of affairs, and I'm looking at the Big Picture and what this means in terms of gaming strategy for MS.
You want to separate the two and I see them as the same thing, only different points on the continuum. Sure, BC has all the impacts of trying to move 360 users to XB1 and all the extra benefits for XB1 users that won't result in new sales.
I don't think that MS spent a year and dedicated all those software engineers towards BC just to help boost their hardware sales. They did it because they were able to transition from hardware to software based platforms. If you can play your 360 games and interact on Live through a software based emulator on the Xb1, you can absolutely make that same thing happen on a PC. If you can do that with the 360, why can't you also do that with the XB1 games? In fact, that's what MS has said with cross-buy, cross-play, etc.
Sure, there's value of BC in terms of trying to get people to move from the 360 to the XB1 and retaining their gaming catalog, but I don't really think that's the main point.
