I wouldn't think they are "walking away" but there is probably is a limit to many of the types of tools that fit the M12 platform, though recent battery power increases may help with that. I have been after them for a long time for some type of M12 cutoff tool either 3" disc or maybe a 4" paddle switch grinder.
They really do have pistol style impacts, drills, and power screwdrivers pretty well covered

and I was happy when they released a right angle impact driver last year and that does spec close to the original M18 version. Still it disappointed there was no sq. drive option. I also have the M12 grease gun over the M18 model But If I was going to buy a cordless band saw or a rotary hammer tool I go bigger. The Fuel circular is ok for what it is and 5 3/8 saws have their place with me but honestly I couldn't imagine them doing anything bigger on that though
Overall it still is a pretty wide line though some of it is pretty pricey like the visual inspection tools, heat gun, scanner etc.
Maybe we should make up a possible list of suggested "new" tools for the M12 platform.
Really has been a lot of focus on lighting, hand tools. and sound, along with the clothing lately though.
