A quick one to those with DTKs.
Does Rosetta v2 support 32bit intel apps, or does it only support 64bit apps?

Rosetta v2 only for 64bit apps?

64 only. It would be weird for Apple to drop support for 32bit only to reintroduce support via translation.

Apple depreciated 32 bit apps for over a decade and fully discontinued being able to run them on OS10.15 at the end of last year. Here's an article about it.

So the answer to your question is most likely it only supports 64 bit apps.

Cool. Thanks for the link as well. 🙂64 only. It would be weird for Apple to drop support for 32bit only to reintroduce support via translation.

They really need to start publishing a list of major developers who are offering dual binary support along with a list of applications working within their Rosetta V2 platform.

Why?
Anyone can do this. Just put up a topic here and get people to contribute to it.
Will be probably simpler to make a list of applications not working with Rosetta.

64-bit only. As others have stated, you're not going to have Catalina drop support for 32-bit Intel binaries only to have Rosetta 2 re-introduce said support. I'm pretty sure this was all a part of the plan and that, as a result, more things will work in Rosetta 2 than did in its PowerPC-to-Intel predecessor.
Considering how closely timed this was with Apple dropping support for 32-bit Intel applications, it's very likely that most 64-bit Intel applications (obviously excluding Intel native versions of Parallels, Fusion, and VirtualBox) will just work and that such a list won't be necessary.
