Usually, increases in adoption brings about lower prices all around for newer technologies. Sadly, that isn't holding true
for DDR2 at the moment. Samsung, one of the largest DDR2 manufacturers in the world, is having supply issues, or at least aren't supplying with the market with enough, resulting in a price increase across the board. Samsung's intense focus on other technologies, especially NAND, may be part of the reason. As the year moves on, we'll start seeing more and more devices utilizing DDR2, and Samsung will definitely follow with market trends. Within the year we'll see Samsung and others start showing off 90nm parts, and perhaps the availability of DDR2 on AMD-based motherboards after M2 makes its debut.
