Many companies are still using Office 2003, and have not adopted 2007 so I'm not sure if 2010 is going to sell well. I personally got used to the layout in 2003, going to 2007 was frustrating. I guess I'll wait a bit more till I install 2010. Only issue is my new core i7 64 bit Win7 laptop has Word and Excel 2010 installed, not the whole suite so I still am not sure if I should install the rest of 2010 or remove it and stick with 2007.
