Going back to the original poster question - or part of it - "the Wilderness in particular".
At this time, there is NO 2025 Forester Wilderness. The Forester Wilderness is still the 2024 SK model and is new. It is not the new body style, it's not the oversized touch-screen and still has knobs and buttons for some features (HVAC, seat heaters, etc.). Given that the only truly unique parts between the rest of the Forester line and the Wilderness is the suspension and the programming of the CVT, I'm not sure why they didn't offer the Wilderness for 2025. Yes, I know that there are model specific trim pieces (the copper trim, the badges, the flat-black hood decal, etc.), these are not unique mechanical pieces that are a bit part of what makes the Wilderness unique. Truly, anybody could walk into the local Subaru dealer and order Wilderness badges, wheels, the hood decal and so on, pop them on a Premium or a Sport or a Limited and who would truly know the difference at a quick glance?
There has been no reference that I've seen for the SL generation (the 2025 models) for a Wilderness model. The basic 5 (base, Premium, Sport, Limited and Touring - US trim) are it. There have been announcements of the new (to North America) Forester Hybrid, but there has been no real information as far as release dates, pricing, trim level, equipment, etc.. There has been a lot of speculation, but nothing concrete from Subaru (at this time).
It may be (speculation here) that the Wilderness doesn't "fit" with the SL generation and will not return. But who knows? Could be that they're planning for the Wilderness after the release of the Hybrid model(s) or maybe for the mid-cycle refresh in 2027 or 2028... Again, speculation and "who knows"....? Maybe they just didn't sell enough of the Wilderness models to keep it around (remember the demise of the XT). Maybe they want to make the Forester Wilderness more like the Outback Wilderness and pop the 2.4 DI Turbo under the hood... Again, who knows?
From what I see on the local dealer lots and on the roads near me, the Sport and Premium still seem to be the trim levels that sell the most, followed by the other trim levels. Remember that dealer inventory for most of the country is based on what the dealer orders and will sell in their locale. In some cases, they may be offered some bigger deals on other trim levels that are on the ship coming over or already landed at the port that are not already allotted to a dealer.
