Yo
This ride and all the stats are all from an article posted when the park opened its new inverted coaster on Christmas Eve.

Pretty much as soon as the ride opened they announced a launched coaster for the following year as well as a picture of Bullet Coaster from Happy Valley Shenzhen. While there is not really any confirmation the ride is an S&S the park is owned by OCT who own the Happy Valley franchise and have built 3 S&S launchers so far and they do talk about compressed air launch so its pretty much guaranteed.
The height stats match that of Bullet Coaster and OCT Thrust SSC100 (Happy Valley Shenzhen and Wuhan respectively) but the launch speed seems a little off. But its early days and Chinese news outlets aren't particularly known for getting their stats spot on.
That's all the info that's shown up so far but shall be keeping an eye on it.
Edit: looked into it a bit further after you mentioned it as it has been a while. Seems it will be S&S according to this article
