Camoflage may indicate it is under trials/evaluation, not yet inducted. There's no PLA insignia either. As for what exactly it is, the hull looks pretty short, but the Type-99A2 hull is about 1 meter shorter than the Type-99 hull. The Type-99A2 hull is based on the MBT-2000 hull, so I wouldn't be surprised if it looked similar. I think this may actually be the Type-99A2, the first clear full body photo. Its timing is not surprising, considering the CG just came out.
