Doubtful. It's saber-rattling. Same with the constant scramble of the airforces, same with the provoking in the South China Sea. Taiwan is in a good position where if China does try any shit they have 2 strategic assets

1. Treaties with Japan, Philippines and SK. This might not sound like alot but the fact that Japan and SK have ramped up aircraft carrier production to meet China's isn't a coincidence. You might think that these countries would do nothing if Taiwan was attacked, but they know that it's the first domino.
2. Probably the most important is TSMC, or a multinational superconductor company. If Taiwan stops supplying China with Super conductors, which is responsible for manufacturing a 3rd of in the world, suddenly electronic factories in China stop, local consumers can't by anything new and as a result blame their government.

The fact that Taiwan has also stepped up local arm production to not rely anymore on American arms-deals goes to show the shift in focus of everyone relying on America and instead needing to fend for themselves. Taiwan has friends, they have to pretend it doesn't exist though for it to exist.
