is it the new unanounced mini steam deck in the box in the middle?

Mine prepared to ship saturday, shipped sunday arrived yesterday. The GLS tracking didnt change but I had an update from Parcelforce stating when it would be delivered.

I had the same thing. I ended up opening it up and disconnecting the battery. Connected the power cable then booted it up. After 5 mins or so it loaded up. Did a shutdown and connected the battery then powered on again.
