I think Wilson is planning really long-term and really seriously thinks that Camilli is the one that could be a future champion. He is probably totally tired of having these 'good' drivers and wants one that shows the potential to be 'great'.

Plodding along finishing last of the WRC teams is only acceptable for so long before its time to make a big change and try to develop someone into the best driver.

There's just no point in M-Sport staying in the WRC otherwise.
