Seeing all this, something tells me that we won't see 2003 for another little while...at least not until another month or 2 until the tests with the 2002 is completely over. It also makes me wonder if Huitong's information is completely accurate. If he is, then maybe we can speculate that 2001 and 2002 is meant for testing certain basic flight characteristics, basic avionics, flight controls, and these basic stuffs like weapons bay. Afterwards the incorporation of maybe prototype 2003 would include some differences, or where real and more advanced stuffs begin. Either way, I look forward to see what else and how long they will use the 2002 before 2003 comes out, and whether Huitong's prophecies ring true.
