But since the TS60 is a new machine, there are no 168mm x 20mm x 1.8mm blades available for it just yet, apart from OEM ones - and Festool are charging $115 a pop. I totally get that they're a premium manufacturer etc etc etc etc ...... but they're charging that price because right now - they can. It's 100% the power tool equivalent of the inkjet printer scam, where you can go buy a beautiful new fully-loaded printer for $99, but then be forced to pay $49 every time you need new ink cartridges.

Sorry. You are wrong here.
Festool is chargin what they are charging because IT COSTS THEM about as much to (have) manufactured these blades /plus R&D plus shipping etc./.
Last I remember these were Leitz-made. Or some other same-level maker. Basically the best quality stuff one can get.
And no, $20 blades in 2.2/1.6 mm are not "the same" as 1.8/1.2. There is a world of difference there. If you had the equipment to test them, you will find out pretty fast. Starting with the disc steel material, ending with blade geometry precision (more so after a lot of use).
This is no "defense" of Festool being cheap. They are expensive, Leitz-expensive. Just more available.
I also buy blades from a local blade maker. And guess what ? This is a reputable company (like 100+yrs old) so they DO NOT make 1.8/1.2mm blades. Their normal blades are 2.8/1.8 or 2.5/1.8 and they have a special "Festool" range at 2.2/1.6, which suits me. That is about it.
Their blades would be "offshore" to you, but still is a traditional company so $40 ($30 sans taxes) for a 160mm 2.2/1.6 blade it is. No way they can makde those blades $20 (with taxes) at the same quality. Compared to the Makita blades I made a mistake to buy twice, they are like a Mercedes to a Daewoo car.
The demand is there for sure - they actually started to stock the CMT 1.7/1.1 mm blades to cover the thin-blades demand on their eshop. I got one of those for a tracksaw without a riving knife. Bad idea. That $40 thin blade is unusable for anything but thin plywood. It just wobbles too much in non-homogenous material.
So I asked for thinner blades /from them/ and got told this:
"We would need special steel for the thin-disc blades. Also neew fancy equipment to handle such steel at our plant." And guess what ? They do not have such equipment - and do not plan to as their bread and butter is in industrial blades. This means they could not make blades
with the required behavior so they rather not make them.
Above aside, I see no reason why the TS60 K could not handle the 160mm 2.2/1.6 mm blades from the older TS55 series. The arbor is the same and there is no riving knife. So safety is not /directly/ affected. The 2.2/1.6 blade is a little heavier, but has a lower diameter, so the forces the saw would face are mostly equivalent.
Putting my math hat on:
(1.6*160^3)/(1.2*168^3) = 1.152 => about 15% more rotational momentum from a 160/1.6mm blade versus a 168/1.2mm blade. This
sounds within sensible limits as far as shaft loads go.
Would me similar like me (ab)using a 350/3.2 mm (disc) Leitz industrial blade (€500 a pop!) in my Protool CSP 145E which officially takes a 380/2.6 mm (disc) ripping blade only.
