We are expecting Microsoft to launch Windows 8 in the second part of 2012, probably around September October time, but now according to a recent report by ZDNet, Microsoft may deliver Windows 8 RTM (Release To manufacturing) in April of 2012.
The report also says that Microsoft will release the first beta of Windows 8 in September of this year, at the Build Conference 2011, which takes place from the 13th to the 16th of September.
According to the information Microsoft will also release Windows 8 RC (release Candidate) at the same time as it release Windows 8 RTM, which would be April 2012.
We are looking forward to Windows 8, it certainly looks very interesting from what we have seen so far and are especially looking forward to see how well the OS performs on tablets and touchscreen devices.
