I've been predicting that manufacturers will be replacing all of their circular saws with plung saws like the Festool plung saw. Now I see some signs of it happening I know Makita has been selling a plung saw in Europe for a while. Now many manufacturers are putting their circular saws on sale. I'll bet plung saws are right around the corner. I'll also bet some companies will also try to get a lot more for them than their equivalent circular saw (they are alll just salivating at the prices Festool can charge) but lower prices will prevail eventually.
Anyone want to make a bet? I'll put up a LARGE bag of sawdust against your old circular saw - any brand, any model- that we'll see plung saws by the end of the summer.
