At the moment nothing has been definitively communicated from Porsche about a new model. It is speculated that there will be a fully electric version of the Macan. The Macan, Cayenne, Panamera etc. will be electrified (expected). Porsche would like to keep the 911 with a petrol engine as this is the iconic model for Porsche. The 911 will be the last in the lineup to turn electric, or even not at all.
The Taycan Cross Turismo (wagon) version is due out end of this year according to Porsche, but with the closure of factories and all due to the pandemic, it may well be shifted into early next year. I would be surprised if there aren't new owners of the CT driving around this time next year. (And, yes, the Macan BEV is the next Porsche BEV "model", due out in late 2022, according to Porsche.)
