Limited Run Games has posted an update on Twitter confirming where the physical copies of Panzer Dragoon: Remake are at:
Standard Editions of Panzer Dragoon Remake have arrived in our warehouse. We will start shipping these as soon as we can.
Classic Editions should arrive with the next 2 - 3 weeks and will also start shipping as soon as they arrive. Thank you for your patience.
The standard edition has been reported to have started shipping. Thanks to B Trizzle for confirming this:
I received an email today that Limited Run is shipping my pre-order of Panzer Dragoon Remake for the Switch
It is just the standard editions that are shipping at the moment; some community members on our Discord ordered the classic edition and haven’t received any emails about shipping. But that wait should also soon be over.
