Hm, never expected to see a proper flight sim on XB1. Whether it will be one of those is debatable.
As for the 'nXtbox'? I don't like this focus on multi-device functionality, because as a gamer I personally only give a toss about a big TV screen and the best possible audio (almost always via headphones). I've no desire to game on other devices.
MS have made some interesting pro-consumer choices of late, partly due to simple lack of alternatives (especially as Sony seemed to be doing their best to annoy people as a company for a while). Far too early to know what to really think, especially from the company who endeavoured to 'lose' the console market clash before they'd shipped a single unit with their suicidal Mattrick-era launch.
Oh, nice to see them updating the Elite controller - that was a good surprise, as with MS Flight Simulator. Not entirely sure it's worth getting an additional, pricier version when mine's still working fine, but I'll likely upgrade (er, sidegrade?) if/when it does fail.
Oh jeese...
You didn't cite anything that compares to Elite (on console, for obvious reasons), nor did you cite any 'online MMO' (which is also entirely SP) which has done what I pondered, re a high degree of persistent progress in a 'sequel' - across PC and consoles. Tick those boxes, and you can resort to one-liner snark.
