Man! talk about ups and downs... I came back and saw the "new photos" of seven J-15 on the CV-16 and got so excited and only to find out a couple pages later that it was fake...
About the lack of info/photos of the CV-16. I concur with most of the posters here in that the most likely "hypothesis" would be an increased security compounded with the fact that the CV-16 is out to sea a lot more than before when it was stuck in dry dock for everyone to see. At this point, it would be virtually impossible for the Chinese govn't and PLAN to back out of the carrier program. I mean, let's face it. the Chinese govn't is NOT an 8-year-old boy who thinks he loves baseball, makes his mom and dad buy all the gear and gets bored after playing a couple games. Like any govn't, they gathered as much info as possible and debated and debated and debated until they made their decision. Once the decision was made, they would be full steam ahead. IMHO, they have long passed the point of no return. They have invested too much of everything, time, money, manpower, pride, for them to back out. At this point, the hypothesis of PLAN backing out of the carrier program is as impossible as the hypothesis that the CV-16 has been abducted by the aliens.
I'm not here to rub anyone the wrong way, and I am fully prepared to concede I am wrong if things turn out otherwise such as if that picture was real, but I don't think a correct read of China's strategies and circumstances today will have the carrier program as a priority.
My hypothesis is not that China completely abandons their carrier program but that the Liaoning is going to continue to be the sole Chinese carrier for many years to come. While I am sure they will make full use of it to hone their carrier operations, expanding the carrier program will very much be on the backburner until the rest of the PLA and China's security environment are at the point where Chinese carriers can be leveraged to make a meaningful difference in combat without undue sacrifice. By that I mean the time when a Chinese carrier can survive and play a productive part in a hot war with top tier opponents without China having to compromise elsewhere in its defenses to effectively deploy the carrier.
In order to get to that point there are plenty of other things the PLA and China have to work on so it makes no sense that they would make the carrier program a priority, especially since carriers have a very specialized role and are not very useful outside of that.
