Question about Saeco Pico Baristo Deluxe

As far as I can see (e.g. on youtube), 5573 was already available in 2018 and the only difference is stainless steel. (5570 is black, 5572 grey). So highly confusing different numbers (where one then falsely assumes it is a successor) there is also with Melitta Solo which I just ordered, also there only colour differences. (So the black one is currently the cheapest:-)

Unfortunately, our source of supply is not yet able to provide us with any information on the availability of the model M5573/10, as he himself has not yet received any details from the manufacturer.
