^maybe it'll push congress to save the F22.
It's like a 5th-generation F-111. Smart move really.
Surprise news here is that the prototypes at least will be powered by Russia's 117S engines as being used on Su-35BM, Su-34 (future production batches) and PAK FA prototypes. Didn't think Russia and China were all that buddy-buddy in the arms transfer dept. these days after China reverse-engineered Russia's Su-27 and Su-33 designs for their J-11B and J-15 programs. Maybe Russia really is just that hard up for cash.
In the long run even 117S is undersized/powered for this sort of thing and its indigenous WS-15 replacement is going to have to be a real monster to get the T:W ratio and supercruise perf. up there. Waiting until all the ducks are in a row would be a mistake, though. China is doing the right thing here.

China doesn't want a reduced US military budget, it enjoys watching the US spend itself into an early grave, it merely hastens the arrival of an age in which China is indisputably ascendant over all. The unveiling of J-20 at this time is designed to forestall any sudden bouts of American fiscal sanity, and it is likely to succeed in that goal.
What is it that you've heard about the 117S that makes it so bad? I was under the impression it was reliable and could deliver 140 kilonewtons dry, which is better than the F-22's engines (104 kilonewtons). Also without raw data the thrust to weight ratio can't be obtained; the thing could weigh 50 newtons or 50 stones for all we know.
Considering that the J-10 took from 1988 to 2004 to enter Initial Operational Capability with prototypes flying from 1996 on.... that's longer than projections for the entry to service of this new and VERY different fighter. I'm willing to give it 8 more years before IOC at a mininium..
I don't know how anyone could get 50.
It's a nice-looking plane.
