Interesting, yeah. I'm mainly interested in making multi-material faster without upping to the size of an XL, so it looks like the Prusa solution would be a better fit for my needs personally.

If Bambu are only swapping nozzles it also means they still need something AMS-like to swap the filament path, which somehow feels a bit clunky. I think having seperate filament paths is overall a cleaner and simpler design.

Someone's made an animation of how they think it'll look like: https://www.youtube.com/shorts/YNSlx0GJ5Ig
