Based on my knowledge, the FLOAT concept store in Shanghai, China has been under development for several years and is still not open to the public. The exact opening date has not been officially announced yet.
It’s hard to predict whether it will eventually open or not. However, considering its prolonged development period and lack of updates from the company, some people might speculate that it may be canceled or delayed indefinitely.
Please note that the information provided is based on publicly available data as of my knowledge cutoff date, which might have changed since then.
