Too stupid requirement

I accidentially went to Visual Studio 2010 and .NET Framework 4.0 Pre-release site and I found out
too stupid requirements of framework

System Requirements
* Minimum 75 GB available HDD space (OMG)
* We recommend that the host computer CPU be at least a Core Duo 2 GHz processor. (Oops! What a crazy requirement!)

and also want people to run under Virtual PC 2007. Its mean they cant guarantee to rollback your system, once its installed. LoL!
