If a new Virus comes out, I doubt the price will go up. They will probably do what Apple does when a product line is refreshed - keep the prices similar and discount the old models until they run out of the discontinued stock. From some of the posts here it sounds like they are discounting the old Virus TI out of the pipeline already, so that would indicate a new model on the horizon.
Incidentally, technology has a great way of getting cheaper and better over time. My original Mac Quicksilver G4 tower cost me $3,200 with a 933Mhz G4 processor, 512MB of RAM, and a 17" cinema display with 1280x1024 resolution. Today, you can buy a 2.8Ghz Quad-Core PowerMac with 2GB of RAM and a 20" cinema display with 1680x1050 resolution for $2,898 - and that's including seven year's worth of inflation and the staggering increases in energy costs. Taking inflation in to account at 3%/year, that's a hell of a lot more computer for about $1,000 less!
