Critor broke the news this morning over on TI-Planet with a full article going into the advertised specs and some speculation about its hardware. I strongly recommend you go take a look at that thread to get all the details but here is a summary of noteworthy points:
It seems likely this contains the hardware of a TI-83 Premium CE Edition Python given the advertised specs and the relatively small amount of time between the release of that calculator and this one.
I'm surprised they decided to stick with the TI-84 Plus style case (like the TI-82 Advanced because they haven't removed it, but I'm not so sure about that because the newest we've seen was manufactured in early 2018.
It will have an exact math engine like the TI-83 Premium CE and TI-83 Premium CE Edition Python.
Of course, like the old TI-82 Advanced, the Python Edition will have the USB port on the top, so it can't be the exact same PCB as a TI-83 Premium CE, but I would expect just a rearranging of the board rather than a full redesign.
Just like the TI-82 Advanced, there's no assembly language support.
As soon as the calculator is available, you can rest assured that a more in-depth look and teardown will be available on Cemetech and elsewhere.
