In all of their releases for the new platform they are starting to really hype up how it is designed for future hybrid and electric power plants as well so they may be headed in a different direction than what we expect.

I largely agree with you. I think we'll see an FX20 and FX25 block, with different head and induction packaging combos. (Likely a performance head, and an economy head, design it all to hold boost, and use a headgasket, or maybe a different head casting to differentiate compression.)

I sort of liken it to how GM has the LS in everything from luxo-cruisers, work trucks, sports car, etc, all just packaged a bit differently.

If we look to 2007ish in Subaru history, the EJ25 NA, EJ25 Turbo, and EG36 were the only motor options.

Now, we have FA20, FB20, FB25, EJ25 turbo, EG36, it's really unnecessary.

Even simplifying it to a product stack like 07-ish would have huge cost savings. I still can't believe the EJ25 is still in production.

Simplifying it to a 2.0l and 2.5l block, both built to take boost, and using a variable head casting I *think* could make a lot of sense in simplifying the product stack.
