ATM, the only mount that is being 100% removed next expansion is the Kor'kron War Wolf from defeating Garrosh on normal. That is being removed next expansion, as has been stated by blues numerous times.
The Gooey Sha-ling, and the Putridus LFR pet may be harder to obtain next expansion, due to not being able to que for LFR at higher lvls. I would focus on grabbing them- you have to do Putridus in the LFR, but you can do Sha on Flex for the Sha-ling.
Elegon may potentially be soloable next expansion.
Other then that, Galleon will be soloable next expansion. Sha will need the MC fixed to be soloable. Oondasta MAY be soloable at very high gear lvls. Nalak is currently soloable, it takes about 15-20 minutes though.
But yea. The 2 raid pets not obtainable through normal difficulty, and the Garrosh Normal mount. Other then that, all pets/mounts will also be obtainable next expansion.
