Which product will be released as the successor when the Jetson Nano is discontinued at the end of 2026?
There have been replacements out for a long time. Replacements are also outdated. The current generation is either the Jetson Orin Nano or Thor (but the Thor Nano version is not out yet). This is the “Super” version, which has higher clock speeds (I think one of the regular ones works as “Super” if you just update the software, but I’m not certain of that):

You can see a list of various versions in the L4T release compatibility chart (L4T is just what you’d call Ubuntu after adding the NVIDIA drivers; L4T gets flashed, JetPack/SDK Manager is the GUI front end to the flash):
