Microsoft has said that the Release Preview of Windows 8 will be coming in the first week of June, confirming previous rumors. The announcement was made at the Windows 8 Developer Days conference in Japan. We still don't know when the final consumer version of Windows 8 will be released, but it looks like things could still be on track for the rumored October launch. Details are thin on the ground as to what the Release Preview will feature — we heard before that it could expand Marketplace support to 33 more countries, but if the Consumer Preview's success is anything to go by a lot of people will be counting down the days until the new build's release.
