Skyactiv is not just an engine upgrade. It's the brand name for a range of technologies:

SkyActiv 1 wasn't dribbled out to old body styles. It coincided with an overhaul of the entire Mazda line. If SkyActiv 2 is a significant step change (which it's purported to be), I just don't see them dribbling the tech out as incremental updates to the gen 3 bodies...or substantially revamping to Gen 4 bodies built on the SkActiv 1 platform for one year, and then slipstreaming SkyActiv 2 a model year later.

Remember though they did "Beta" test the first Skyactiv engines in the second gen 3 before the CX5 release. They didn't have the trick exhaust manifold or the body structure, so it's possible that for test and reliability sake they may deploy Skyactiv 2 engines in Skyactiv models. If I were to guess it maybe the 2017 CX5 is the test mule for Skyactiv 2. IMO

The Mazda3 will be getting the new engine first.

Exclusive: Mazda's new engine boosts fuel efficiency by 30%- Nikkei Asian Review

Mazda plans to incorporate the new engine in 2018 in the new Mazda3, dubbed Axela in Japan, which will undergo its first overhaul in five years. The engine then will be adopted gradually by other models. The automaker positions the engine as the second generation of its Skyactiv suite of environmentally friendly technologies, which were introduced in 2011.

If they can actually make HCCI work on gasoline it will be a material step forward. I don't know about a 30% efficiency improvement (that's aggressive), but in the ~20% area over existing "high-tech" engines (E.g. Skyactiv today) is within the realm of possibility.

Essentially it's a diesel engine that runs on gasoline. These have existed for a LONG time -- the military had a diesel that had a special high-swirl combustion chamber and COULD run on gas (along with diesel and kerosene derivatives such as JP8), but it suffered terrible service life, had crap for economy, lower output and sky-high emissions if you used it. Basically it was possible to fuel it with gas in an emergency if you HAD TO, but it definitely wasn't what you WANTED to fuel it with.

This has been a nut plenty of people have been trying to crack for a good long while. It'll be very interesting to see how well Mazda does it.

I found something about a potential 2018 version here, but it even says that it might come out in 2019.

Yeah that doesn't say much except "how lazy" Mazda is. Anyone who thinks Mazda is lazy needs to reacquaint themselves with the definition of lazy. An automaker who comes back from the brink of death by totally reinventing themselves is not lazy. Maybe cautious and conservative, but not lazy.

Click-bait site. If you try to pull up "2018 Mazda 6" on a search engine query, you will get mounds of these click-baits. Some just bombard you with ads, others hide various malware. Tread carefully.

Agreed 100% and they have done a fine job to say the least!

Totally agree about the cautious and conservative and couldn't agree more about the lazy part as well. They are far from that
