You guys do realize that you have totally hi-jacked poor PutnamEco's thread on what would become classics. I think that any power tool that has a all metal case has a better chance than those made of plastic.

I think the all metal case power tools are already classics, actually. They are illegal to manufacture in California, at least, and I can't remember the last time I saw a new one for sale.
It's hard to imagine a currently made tool becoming a classic in the future. New innovations seem to have the life-span of a mayfly these days.
