core duo is like Pentium 1 Dual core- if it exist
core 2 duo is the Pentium 2 Dual core

core solo is the single core version.

the announced price cut by intel is for reference only. they can't force retailers to sell at that price unless many retailers fixed a price then it's a crime, price fixing.

but if many retailers already sell it at lower price, any sane retailers will also sell at lower price just to be competitive and since they got the supply at lower price.
