Just on a side note about memory prices and consoles ...
One of the reasons consoles (generally) have far less memory than their PC counterparts is that console manufacturers tend to favour higher quality memory over higher quantities of memory. As a result of this, it makes more sense to look at the price of DDR 3 in the 2000+ range than it does to look at the price of DDR 2 memory in the 1000 range.
While Nintendo might not choose to use DDR memory at all, it is likely that the memory they will choose will be fairly high end and similar in cost to high end DDR memory. The reason for this is that memory access is very costly, and in high performance systems memory tends to act as a bottleneck. Often real world performance can be dramatically increased in a system without increasing theoritical processing power of the CPU/GPU simply by using much faster memory.
