There are reports out there suggesting that Nvidia will be launching about 6 new 8000 series video cards on April 17th. Apparently some of these video cards (or maybe all 6) will be hard launched on that day. NGOHQ.com tells us that the 8300 GS, 8400 GS, 8500 GT, 8600 GT, 8600 GTS and the 8800 Ultra will all be "released" on the same day. They go on to spread hope to the AGP faithful by saying that Nvidia will be launching AGP versions of the 7900 GS and and 7950 GT soon as well.
X-bit labs also has a few things to say on this subject.
