Thanks, I was just getting confused as I could swear I read somewhere that the boards would have slots for both types of memory.
Some probably will.
Basically once all the manufacturers have started to produce them there will be three types on the market:
P35 - DDR2 Only Support
P35 - DDR3 Only Support
P35 - DDR2 & DDR3 Support (Only one type at a time, no mixing)
Because there will be a lot more work involved with creating a board with both memory controllers and a way so that both DDR2 & DDR3 module slots can be mounted, expect the boards that will take both types to be rather expensive.
However it does give you a cheaper upgrade route as you can stage it.
Buy motherboard now and use DDR2, move to DDR3 over time as and when prices appear and then drop then look into the new CPU's at the back end of the year.
