I don't really give a flying fuck about sales, what's more important to me is mindshare and the way the Xbox senior management team have revitalised the Xbox brand in general should be commended.
From hardware iterations like the S, the X and the Adaptive Controller - they've nailed it all.
From the services front like backwards compatibility, crossplay, refunds, gifting etc - they've nailed it all.
Then it's the games, there no denying that just two years ago first party was in trouble but with the acquisitions, team building and general hiring sprees all the studios are doing - they've nailed it all, probably.
The transition into next gen could have been horrendous but they have righted most of their wrongs and have now built up a lot of goodwill which should help them with mindshare when it comes to launching Scarlet.
Exciting times ahead no doubt! :)
