Are you experiencing any issues with your current setup? I ask because, you're right, things are moving really quickly.
If you aren't having any problems, it might be worth watching the marketplace for a while before upgrading your hot end. Especially if you want a multi filament system, you might eventually want to buy an additional printer.
I also run an Ender 3 V2 v2.2. it prints TPU pretty well without a direct drive upgrade. I'm still running the original hot end. No auto-leveler, no dual-Z kit. I upgraded the main fan, the springs, and the extruder. I added a Z stabilizer.
I've printed quite a bit with it - PLA, TPU, PETG. So, the original hardware can accomplish quite a lot without major upgrades.
I'm not saying this to dissuade you from upgrading. Upgrading is fun!
I'm saying this in case you don't realize how much the printer can accomplish without upgrading. The 3v2 is a beast. Is it perfect? Heck no.
But you didn't mention anything about being unhappy with the output. So it may be worth tinkering more with what you've got before you start swapping more parts.
