I have no information, but my opinion is don't hold your breath.
TCL / Alcatel seem to be doing OK in their niche. I expect the Palm brand was going cheap and they snapped it up with an idea to give themselves a cool brand make over. They talked the talk about asking the "Palm community" to get involved in producing new, innovative products, but at the time we all took the view that this was just talk and cynically assumed that any new product would be the badge slapped on an Alcatel "me too" Android phone - especially when they stated that webOS wouldn't be used.
What is the "Palm community"? It's either the engineers & designers who made the original products or it's the customers or both. The former employees seem mostly gainfully employed in other tech businesses and there's been no official communication with this forum - which seems to be the obvious place to find Palm customers.
There may be a secret project of which we are unaware. It would be strange for TCL / Alcatel to make this public announcement with out actually starting something internally and to be fair, it might take a couple of years to set up a project / subsidiary and get a viable product. But if we assume that there are few or no ex-Palm people involved and no one's asking us, then what would a new Palm product be like?
You can see from the trials of Jolla, Blackberry and even Microsoft Windows phone that the market has reached a state where any new phone pretty much has to be an Android phone (if you're not Apple).
Palm was in the Handheld computer / smart-phone business. Alcatel is in the phone business. They could make some kind of hand held or phone. If a phone, it's likely to be an Android, but it could still be a quality piece of hardware, a bid for the high-end. But differentiating from the flagship products of competitors will be a problem.
The other option could be in the new kinds of 'Smart devices' like watches and other wearables or home automation or maybe there's some new product type to be found? If Alcatel really try, they could produce something worthy of the Palm name, even if there's no real connection to the past other than that name. The Bugatti Veyron may be an example here! Of course the very word, 'Palm' suggests something that is hand-held.
My total guess in order of likelihood:
- Unremarkable Android phone.
- Really good Android phone.
- Some kind of wearable.
- Something totally new or a game-changer in an existing market.
