Microsoft better pull it off swiftly and efficiently this time
Just like everybody was hoping for... the time before that, and the time before that, and the time before that...
As you can tell, I for one have little faith in MSFT's abilities to do anything swiftly and efficiently, my personal experiences with all their updates on Mobile and PC attest to that. And even if they pull something off who's to say they won't be having a change of heart a few months down the road like they've been doing the past few years. Hard not to be skeptical when you think they "got-er-now" only to have them decide, "naw, that just not quite what we were looking for".
Like anything in this world it can always be better, but if you're always changing direction/retrenching then it'll amount to very little. And if MSFt is claimed to be the "software guru" why can't they seem to devise a plan that sustains forward momentum? Obviously they haven't been able to do that up to this point which tells me, they haven't a clue.
So "YES", IMO they are killing everything and chances are it'll likely include any new reincarnation(s).
