Who know ? Microsoft can release the "th2 update" for 10240 as a big cumulative update... I don't want to say "service pack". There is no such reason to reinstall Windows 10 on casual PC's with a 2,8xx Gigabyte download.
th2 is certainly going to be a cumulative update for those using the RMT build 10240 and there will be updated iso/ESD for those who didn't upgrade yet like they always do and did in the past. What I'm saying is Microsoft isn't stupid to release a build to insider, say 10576, that is time bombed and release the exact same build number for a release that is intended for the general public. Even if it's the same release the general public version th2 will have different build number.
This is stupid. Windows 10 is now a service, so they'll continuously push out "RTMs" along the way. Big fuss over nothing. Move on.
No, sir! But, rumour has it that it will be on first week of November of this year. Possibly, 2nd or 3rd of it.
How big will the download be for Retail Windows 10 Pro x64 users? I only have 2GB of space left, so...
