A new firmware update unveiled some tidbits about the future Tesla S/X models:
New hardware incoming.
Integrated inductive phone charger (Qi) for S/X cars.
Two new S/X battery types in several configs (not yet sure of the capacity – TBD)
new lumbar (so new seats?)
New charge port type.
New suspension version.
I would speculate all these are imminent 1/

It might be that these updates are for the Tesla S “Plaid” version that is definitely coming this year. The interesting bits will be the new battery which is rumored to offer a 400+ miles range!
