There's been some speculation from the computer magazine writers about whether nVidia and its various affiliates would drag their heels on the AGP for mid-level GF Series 6 video boards. Now that the Series 5 cards are selling at reasonable prices, the FX 5700's in particular are selling well. Selling a lot of product for a moderate markup is preferred over a little product at a large markup, and the AGP 6600's, even priced well above the current FX series mid-range, would be likely to kill off that surge in Series 5 purchasing.
Many folks would choose to wait for the costs of either PCI-e MB's, or AGP 6600's, to come down closer to where the 5700/ 5900's are priced right now. Reading those speculations, I thought it made a lot of sense, but there is probably already a sizable market segment's worth of upgraders sitting out upgrades to much of anything other than Hdd size and RAM. Maybe nVidia sees the current crop of "let's Wait for the Next Great THING" procrastinators as too large to ignore?
