1. normally the new jet's first owner would be some regiment of PLAAF Test Flight and Tactics Center...this center has a regiment of J10A already...the elite pliots of this unit would begin to get familiar with this new plane and creat new combat tactics ,write the operation Manual and mantaince manual...
another tradition is :a combat unit , of which the AFB is close to the Manufacture site ,might be chosed as the first unit and seed unit. as we know, a regiment right in Chengdu Military Region was the first combat unit operating the J10. and this unit retired their old J6 and got this new bird around 10 years ago. after hard training this EX- 2nd rate regiment has won the respect and jumped into the first league of fighter regiment in PLAAF formation...so we also thought they might hand over their J10A to another regiment and begin to accept the new J10Bs...
when we saw the tail number of these birds painted ,we would know the answer...

2.J10C is a complicated one...I haven't figure out some important detailed improvements...
some source said the Avionics would be a great leap ... but I don't believe it too much...coz J10B has got a major upgrade.
the reliable source said it would fly by the end of this year or the New Chinese year of 2014(31th Jan )...
we have to wait and see.
-----------------------
BTW I would like to correct my early opinion on the J10B's radar...
it's a AESA,and our first Gen fighter AESA radar...the T/R unit number is around 1250 or 1280 .
the back end of radar is quite compact
