I think the sale will go through and China will do little more than verbal objection, like usual. My personal opinion: Taiwan is no longer a priority for China. China's strategic ambition is much more than simply taking back Taiwan. China is using Taiwan as an excuse to expand its military. So whenever China's expanding defense is brought up, the Chinese can say "hey we want Taiwan and this is our own issue and has nothing to do with others". This way, other nations would less likely to be alarmed by China's military expansion. even Taiwan is still a priority, it is a short term one.
Another thing, China could also be using Taiwan as leverage against the US. Like a bargaining, China can say to the US "hey we've made concession with you on the issue of Taiwan and let the arms sale go through. What can you do for us?"
