In a sense this is the way PLA being "transparent", or intentional leaking. It all starts with rumors which keeps people guessing, up to a point when these rumors become fairly creadible and close to the truth.
To me the rumors about 002 has reached this point, that the project has started "moving", that it'll be constructed at JN shipyard, that it'll be conventional powered, with steam CAT. If it's a guess then it's a reasonable guess, a logical one that fits all signs and PLA planning pattern.
Of course there is always the trap of intentional deception, that if you become relying on these rumors, you may get it wrong sometime. But at least in this case, better believe it than not. People now starts saying the one after 002 will be nuclear powered with EMCAT, now this is obviously rumor way too early and no reason to believe it.
I'm actually a bit surprised that they confirmed 001A this early. They could wait a bit more till the flight deck takes shape. To me this is a strong indication that 001A will be laubched this year, otherwise it's just too unchinese for me.
Basically 001A buys 3 years time for 002 design to mature, that's the way I see it. Consider that 001A is Commissioned in 2012, even if 001A gets Commissioned in 2019, this is still a long gap and it looks to me that they are really taking the time to be incremental and get it right, not spurred by the geopolitical heat in any way.
My guess is PLA Navy will Commission two carriers per decade. This decade, two ski jump ones, next decade, two conventional CAT, then two nuclear powered ones with EMCAT in 2030s.
So prof. Ma will have to wait 15+ years before his EMCAT becomes reality, quite dissapointing if it you ask me.
