Finally. Now I'm able to clean install to Insider Preview whilst retaining my AHCI on Samsung Magician. No more Stable then Insider.
I doubt they will do that. Whole new builds for cumulative patches will just add more things to go wrong with upgrades. If they want data for their day 0 patch, full telemetry should be more than adequate. Hard to say which build will be out on Aug 2 via WU but I don't think they're done just yet.
Yes, it's all guessing, the scenario changed from Insider "RTM" 2 weeks before the MSDN releases (same 10240 builds), then in November it was just 5 days before MSDN and now it can be everything with dona at the wheel
