This will be my 5th LR with the PSA engine and its proved itself to be a reliable unit, the Ingenium engine will no doubt have improved efficiency but for me it's to much of the unknown. It will be great in the new Jag but in a Land Rover I'm not sure, Land Rovers are still too heavy to get the real benefits from it.
All engine production has been assigned to the new Jag, which needs it more than LR, who's sales are through the roof, Jaguars aren't so strong and need something to compete with Germans
So for me, no, it's not worth the wait.
