A few whispers from the Melbourne pitlane suggests that McLaren has a get out clause (effective immediately) for their engine deal with Honda Racing, as it was a deal made with previous McLaren F1 management, which is no longer in effect.
We know Ron Dennis is no longer with McLaren F1, but does that now make the McLaren/Honda agreement null and void?? Was a clause put in by RD that if he was to be ousted the Honda deal goes with him? I guess it's all in the fine print of the agreement. Something for the lawyers.
I'm not sure that McLaren could (or would) dump Honda at a this late a stage. It would be a massive blow for Honda if McLaren were to part with them at the early stages of 2017. And a blow for McLaren financially.
If the divorce was to go ahead, it would take 7-9 weeks to re-engineer the MCL32 to drop in the new engine, depending who McLaren deal with. Could we see McLaren powered by a different engine post the summer break? Quite possible from what the rumours are suggesting.
