Hello Danchiango and welcome to the Best Buy forums
Short answer is no their is no ETA on when Best Buy will receive more Switches
If you wish to receive a notification once more are instock I would recommend going to Bestbuy.com and finding the switch you would prefer and Opt in to receive a notification once they come in stock.
The views that I post are my own and not that of Best Buy. ***Know that I am not able to issue official responses and that my posts are only here to help before an official response is offered by a Best Buy Social Media Specialist***
