I've seen many times where MS said they plan on post Windows Server 2008 and SQL 2008 to be 64bit only. If you don't have a 64bit server by 2011, you have to be trying to not upgrade. With old memory holding stagnant for price drops and new kingston/crucial DDR2-667 ecc memory going for 2x2GB going for $120, how would someone not want a newer computer with those prices?
