I am upgrading but keeping my windows 8.1 intact as well. Sometimes a build is released focusing on certain aspects the last couple I think GUI the last few builds the other bugs a consequence of the other

On top of that to be quite honest I think the free upgraders are basically playing OEM and doing the RTM compatibility tests for them I am not concerned about the lack of time between now and then. We could be 6 weeks or more away from an RC build
