Prefacing this with the comment that this isn't an attack on MSoft but...
According to what freakin metrics? They still won't reveal console sale numbers, and what tidbits we occasionally get indicate that they're far, far behind Sony in terms of install base. And more anecdotally, that's in part because they've not managed to make much of a dent in the EU market this generation, they're pretty much solely selling in NA.
Even on the software side things aren't looking amazing for them this generation, with big misses for blockbusters like Crackdown 3. Even Gears 5, which IIRC is the best selling Gears game, hasn't come close to the numbers of some other exclusives on other platforms (and it has the benefit of PC sales to boot).
Now then, that's not to say they're not positioning themselves for a stronger next-gen, because they totally are with their studio pickups. But the reality is that Microsoft faceplanted out of the gate this generation and doesn't seem to have ever recovered. We're not seeing a repeat of last gen where Sony managed to close the gap on hardware sales by the end of it, we're seeing that gap persist through the generation.
Neither has had "significant" improvements outside of their mid-generation refresh. Microsoft has the better refresh with the more powerful One X that's capable of more native 4K than the Pro, but that's not significantly different and it hasn't made much of a difference in terms of hardware sales either.
Lower shields, power down weapons. Let's keep the fanboy nonsense out of the thread and just discuss the topic.
