Milwaukee just had their pro user/influencer event and one of the biggies revealed is a new 18v Fuel powered track saw. It looks "very worthy" and has some nice features, including some micro adjustability and some stability relative to the track while cutting bevels. Kyle from RR Buildings spent a bit of time with the tool and it's pretty impressive. It's also compatible with existing Festool and Makita tracks which is nice for folks who have saws with tails that want to go cordless. I can see value in that even "in the shop" as it's easier to control one dust hose over both a hose and a cord for anyone who doesn't have a "bonded" hose/cord setup.

They released other tools, too. Here's Kyle's video. The tracksaw talk starts at about the two minute mark.
