Does anyone know if you can pre-order p开发者_Go百科urchase Microsoft Visual Studio 2010 and get the current edition (2008) for use in the meantime, until 2010 launches in March?

If you buy VS2008 Professional with an MSDN subscription, you will automatically get upgraded to VS2010 Premium Edition when it gets released (source).

If you don't want to buy an MSDN subscription along with VS (or you only really want VS2010 Professional), I suggest you use the Beta 2 version of VS2010 (which comes with a GoLive licence enabling you to release and deploy what you make with it) until it is released and then purchase it when it is released in April. You can get VS2010 Beta 2 from here.
