well I just read in Zdnet... huh that site with so many trollytrolls, but we still find MJF there and edbott... BUT anyway.
she says "While I've heard some Microsoft watchers predicting that RTM and general availability of the Windows 8.1 bits won't happen simultaneously, this is not what I have heard from my sources. While new devices preloaded with the Windows 8.1 bits will probably not be out until late September/early October, I have heard that the general availability of the Windows 8.1 bits won't be held back this time around. I think users will be able to get the 8.1 bits simultaneously or very shortly after RTM."
I guess the difference this time, its that this isnt a new OS, its just a free upgrade over 8.0.
Also Im sure Microsoft wants to release 8.1 for surface RT and surface pro as soon as they can. so why would they hold 8.1 for 2 months from consumers, if they are the makers of Windows and Surface? it doesnt make sense, just like I don't think they would release 8.1 only for Surfaces while other users wait 2 months for GA. so I believe in MJF sources, since it makes sense to release 8.1 a little after RTM, especially since windows is updating faster, so the faster consumers get the update the better.
oh I forgot to paste the link of the article if you want to read it :)
