This is just a first ever ITX 3000 series card. I doubt there will be 3070 ITX or higher tier card. But let's wait a bit and see if there are any other manufacturers that may be launching ITX 3060 and 3060Ti variant in the near future.
https://videocardz.net/asus-geforce-rtx-3060-ti-8gb-phoenix - something like this might come out soon. And ASUS proved they can build great cards with this generation. It might be better in every way like TUF series compared to MSI. Also that backplate on AERO seem to be plastic... so another corner is cut for sure.
Gigabyte might launch it's Mini ITX version. But for 2000 series MSI had better cooling / noise performing ITX cards than Gigabyte. And colling/noise is what I care about the most.
It's lost in a couple of threads, but there are two other companies that have announced ITX 3060s. MSI is the only 3060ti though.
