I see a lot of posturing and sabre rattling, but I don't think Xi would make this mistake - there is too much interest from the West in an independent Taiwan and, as it is now, it's not really an urgent matter to settle it.
China always plays the long game. They are not in this for any quick wins, because there is no political benefit from it - their political system ensures popular and populist measures never prevail over long-term strategy.
That's quite an advantage over most Western democracies, where politicians always prioritise what will give them more votes in the next election over anything that will benefit the country a couple terms down the road.
