Let's not forget that the F-22 requires 30 hours of maintenance for every 1 hour of flight, and the F-35 is expected to be similar in that regard.
Yes lets not, the F-22 is a very capable fifth gen aircraft, it is "complex" to say the least. The F-35, J-20, and Pak Fa will require similar love and attention, no? Thats what happens when you integrate an aircraft into a weapons system. The F-22 will likely continue to have issues of corrosion, cracking, O2 problems, as will the other pieces of this little game. On the other hand it is the only fifth gen operational and performing its mission today and tommorow. All these other fine aircraft are in developement, when they come on line they too will face the "is it worth it"? Only if you believe in Airpower, and I do.

Hmm ... maybe I'm too tired today or overanxious to see that bird - upps, Sorry "Dragon" - finally spreading its wings !
But aren’t these two J-20 in that image ??

It seems that there are, they do love teasing us, or maybe its taunting, oh well, I think your right about the second bird in the shadows, and I think you're right about the powerplants. If you were testing an engine in developement, it only makes sense to throw the new one on with the old one. It also of interest to know how those engines are doing in a particular airframe, with cooling, airflows, inlets, etc, etc.
