Why is DDR2 still more expensive than DDR3 ?

[zero80472]

i have noticed something over the last few months

DDR2 is still more expensive than DDR3

for example
Corsair XMS3 4GB (2x2GB) DDR3 PC3-10666C8 1333MHz Dual-Channel = £29.99 with VAT


where the

corsair XMS2 4GB (2x2GB) DDR2 PC2-6400C5 TwinX Dual Channel = £49.99 With VAT

why is this

since the DDR3 memory is better it should be more expensive
