I don't frequent these forums but I browse the site occasionally and I knew I would get a quick reliable answer for my question. I'm looking to get a dual 2.8ghz in the next 6 months and I am afraid to repeat my last mistake: I bought the original G5 tower with a single 1.8ghz then a month later the dual 1.8 came out for the same price. So my question is, when is the next generation of Mac Pro coming out? Should I be worried about screwing myself again or will the current generation maintain for a while?
