Overall I think it'd be fair to say that it was a productive, yet stale release for Mathews. I think they nailed it with their approach to the market. I think (and this is purely speculation) that they saw their main competitors (Hoyt and PSE) marking their flag ship bows up in that $1500-$2000 MSRP price range which inevitably is a tough pill to swallow for the average joe hunter. By staying lower in MSRP, that opened the door to hit their consumers with genuine Matthews accessories and make the difference up there.
Advancements:
Having the dovetail run through the riser is a brilliant idea. Hoyt took a stab at that concept with the picatinny rail system and I think I've only seen one, maybe two sights made for it? Balance seems to be the name of the game now.
The SAS system is a great idea; however, I can't imagine many people ever using it nor more importantly knowing enough about tuning/fixing in the field to use it. It's just a niche product that those who know how will use it WHEN they need it. Maybe a cheap insurance policy, if you will, for the backcountry.
Negatives:
I've only seen 2 common ones.
1. Slower bow. I won't say much on this but if 8fps ruffles your jimmies, then I think you have bigger issues to worry about. That number comes from V3 31' @ IBO 342fps and VX3 33' @ IBO 336fps
2. They didn't do anything to the grip. I feel like I've read/seen a lot in the past few years that the Mathews stock grip is pretty narrow. I think this is more so a personal choice and not something Mathews or any bow manufacture can change and make EVERYONE happy.
As others here and on other platforms have said, I think until something revolutionary comes out, companies are micro-refining specs and accessories. Matthews took advantage of the accessory game this year with the quiver, SAS system, integrated rest, etc...but the price point for some of these is crazy. $250 for a quiver that I can only use on their bow? Maybe it has compatibility with older models but if I, personally, was to pay that much for a quiver, it would have to be a buy once, cry once situation in that I can use it on any bow in the future if I was to ever switch to another brand.
Just my $0.02...
