Intel has a big drop scheduled for August of this year (the Socket478 Fire Sale). Practically *all* the Northwood-Cs and S478 Prescotts will be either fire-sale priced or JPDed (Just Plain Dropped).
Later *this* month, the first LGA775 motherboards and processors will appear (early-bird TCWO is already advertising them in both MaximumPC and PC Gamer). Leading off will be (of course) Intel, with no less than *four* LGA models, all of which will use the BTX formfactor, have multiple PCI Express slots, and *no* AGP slots whatever.
If Intel gets it's way, AGP 8x is in big, big *trouble*....
Im sure after the june 20th launch of the LGA775 (Not 100% sure but some mobo manufactorers calling them pentium 5's) prices should fall across the board.
