"The main problem with "multichannel DDR" is the number of wires and pins required. I expect that embedded DRAM will be used extensively in applications that require very high bandwidth, because it does not suffer from any of the problems of DRDRAM or DDR in this regard."

Main problem of DDR is lack of stability, esp. with multichannel implementations. Of course pin count is another disadvantage.

And just how big a die do you expect a performance MPU with 512MB of embedded RAM to be. How much heat will it produce over what surface area?
