The 361 I just fondled and ran (but not cut with) has conventional construction in the crankcase/cylinder assembly. It's all metal above the rear handle, except maybe the clutch cover (and, of course, the top cover). I couldn't tell for sure on the clutch side. It's a new style cover without accommodation for the outer bucking spike, and it appears to have an inner shape conducive to both chip expulsion and chain retention. The starter cover is definitely metal as the tapped holes for the winter kit plainly show. Rim sprocket assembly was on the saw, and 20" laminated bar with 3/8 RM2 chain. Price tag: $539.00
The saw sounds tinny, as would be expected and the muffler appears quite (casual) tamper-resistant. It's a smooth runner in hand, though, at idle, and it spools up nicely, staying smooth along the way. I don't have any doubts that (at least) after a couple gallons of gas it'll outcut my 036.
The air cleaner assembly is different than the old style split cartridge element. It's a basket about like on the 270/280. Interestingly, the winter warm air port does not feed air to the filter differently than during the summer. It evidently only blows warm (dirtier) air from under the top cover to the back side if the airbox baffle, and around the carburetor exterior.
Looks like it's gonna be a winner.
I don't know if I'd say it looks like Stihl wants "back in the game" since, actually, their timing is probably about right on coming out with new designs in conjunction with the phasing-in of tighter regulations. The whole industry is kind of in a state of flux right now, isn't it?
