My guess is Le Mans only. They'll run out of time to be ready in time for the pre-LM rounds again, especially as the hybrid isn't supposed to be ready before well into the year..
Le Mans will be a disappointment but not quite as much as this year, maybe they can get as close to the front runners as Toyota was this year, if things go really well.
That won't be enough to convince the big wigs to keep this thing running though and the program will be pulled post LM. That's my guess
