I don't know what your missing, the "new Huskies " have been around for 10 years first at Sweden dealers as a 560 and 562.
These saws set the design standard for the "2016 new version II 261, 362" and then later the 462 which is not even available in USA yet.
2014 some Asian friends sent me the first pics of the prototype 442-462. When I posted them for the first time on a saw site in June 2015 I still had no information what it was or what cc. Then 2016 Version II 261, 362 introduced and I can see the similarities to the 2014 pics, then later 462 press release.
Husqvarna has a history of keeping design series on the market like the successful 395XP.
I don't see a gap for Husqvarna. They have a 572, 372, 576AT all in the 70cc class for the professional market of endusers who can work with a saw 8 hours a day 5 days a week without noticing a difference of a few ounces.
Husqvarna still has a 390XP that has a cc displacement niche right after the 576XP. So I don't see any gaps there.
Stihl has something to worry about that their flagship saws are still running old style journal cranks.
2020 will be an interesting time for Husqvarna.
