Here is what Porsche's Press Release stated: https://newsroom.porsche.com/en/2022...ere-27075.html
As the first member of the Taycan Sport Turismo family, the GTS will be launched at the end of February 2022, with further models following just three weeks later in mid-March.
My sales rep confirmed to me that they will be getting the additional models. Official Porsche announcement is coming.
Could things change? Certainly. But this is where things stand.
