Both the CX website and the AM website have just added P class to the MPO earning chart and AM earning chart, respectively, for CX and KA. P class earns the same amount of club points and miles as D and I classes. As of now, P class has been used for business class AD75 tickets, but looks like CX and KA will soon use it for revenue tickets. P class fares will probably be between D class and I class.
