This is actually very very bad. Google's lack of focus/vision w.r.t Pixel all but guarantees that Samsung can eat up the whole high end android phone market. Samsung's desire to stuff so much garbage unto their phones that they are molasses-slow even with the fastest mobile SoCs available to them all but guarantees that for most users, android will remain a huge mess. As an android user, this saddens me.
I think it’s more likely we will see Microsoft and Google taking substantial share of the US Android market over the next 5+ years
As someone else pointed out, the real problem with the Android ecosystem isn't so much the hardware imo it is the absolutely appalling software everyone but Google seems to ship (I definitely include Samsung in this). Microsoft could do a good job of this and has the $$$ to throw at marketing (plus could leverage the cloud streaming Xbox stuff).
