I was at Home Depot yesterday chatting with the local Milwaukee rep and he confirmed that an M12 circular saw will be released later in the year. It will have a 5 3/8" blade and he believes that it will fall under the Fuel line. He told me that he had given a prototype (it's all white in color) to a local contractor that he knows to give him feedback. All that he's heard from him so far is that the contractor is surprised by the battery runtime. Hopefully next time I see the rep he can give me a little more info, like a projected release date.
