The "WPA World 8 Ball" was quietly scrapped and renamed. I asked the same thing back in August when there were all the WPA threads about lack of payment at WPA and Chinese tournaments. It went from being a WPA World 8 Ball Championships in Toronto that was set aside in 2016 to support this new event in China (as the 2017 World 8 Ball Championships), to being quietly renamed & downgraded to the Jinan Heritage Classic 8-Ball which wasn't even confirmed a month out.
At the time if you were to look it up in Google and find last year's announcement the linked page had actually been rewritten to point to this "Classic"...

This was out there from WPA:
Dear All
I am still awaiting confirmation from phone conversations today about the Jinan Heritage Classic 8-Ball event scheduled for Jinan next month. The news I’m awaiting is most likely not going to be good. They did say the event is not cancelled, but wouldn’t confirm if it would go ahead either. If the event is cancelled, we will be seeking compensation, but that’s no guarantee either. Please advise your players of the situation and warn them not to buy any tickets if they haven’t already done so. I will update you immediately something is received.
Thank you - Ian Anderson
