EU-Turalyon(A), multiple others.
I'll have to edit this later if I can find the source, but I think LFR-only pets will be added to the normal loot tables once WoD is released.
Overall, I think ToT/SoO pets are good investments. How good might depend on how strong average 100's will be in terms of solo-ing capability of those raids. Also, I think this mainly goes for SoO, there are a lot of mechanics in place to prevent people from soloing or using small groups; blobs on immerseus, corruption / adds on norushen, prisons / tankswap on sha of pride, towers on galakras and so on.
