I'm not sure. wording like this:

> We anticipate many RStudio users will be curious about Positron.

Heavily implies it as a seperate thing that will continue to be maintained. They haven't said they're getting rid of support for Rstudio.

I think this is probably more that Posit have been trying to move more and more into the Python space, since that's where most data science is happenening. Rstudio has a great but is obviously very associated with R, so making a similarly intended project that is more explicit is supporting other languages isn't inherently a bad shout.

Unless this has recently changed, the support for LLM coding tools in RStudio is so bare bones that I would expect many users to switch to Positron just for that.

It will continue to be maintained, but if lots of R people move to Positron then RStudio's features will start to lag, and they'll eventually deprecate it.
