Soong is a clone, no doubt. In fact, they're all clones. There hasn't been a naturally-born Soong in probably 400 years. And given the state of Arcadia, he's a dirty old man. Or maybe I'm the dirty old man.
Starfleet Command received that message from Picard, even though they couldn't respond, and they're sending a fleet to the planet commanded by Riker onboard the Enterprise-?. Soji will stop Sutra from destroying the Federation fleet next episode, probably through violence.
That body with mind transfer is being made for Soong, of course, who I guess must be dying or just scared of being so old (I guess he's Picard's age? Which adds a bit more to Noonien's backstory, since he's cloning himself thirty years before building androids with Juliana). Soong will die, no doubt, probably killed point-blank by Sutra, and Jurati will offer the body to Picard some point after the climactic battle. Who will then turn her down with a speech about living ones full life or some nonsense. He'll survive, and we'll be going into Season 2 with the terminal brain illness still on the table.
I don't really like the idea of a synthetic mind meld... but I guess telepathy is a biological function, that can be mimicked and transferred if Soong/the synths discover how to tap into the telepathic field or whatever. Touch telepathy is probably much more easier than the remote variety we see from Betazoids or Talosians.
