While the Switch seems to be sold out all over the world and the Switch Lite is quickly catching up, Ring Fit Adventure has been suffering the same fate. With the game requiring a special Ring-con accessory to play, there's quite a bit more that goes into production. Coronavirus has caused production line issues for Nintendo and countless other companies, and the Big N is currently scrambling to produce more units of Ring Fit Adventure through different means.
This all means customers will need to have a bit more patience while waiting for new copies to ship out. While Nintendo themselves haven't said when to expect more stock, some retailers in Europe are claiming the wait is going to be pretty lengthy. A customer in the Czech Republic who preordered Ring Fit Adventure got an email update saying the shipment was shifted from April 5th all the way late Sept./early Oct. 2020.
We'll reach out to Nintendo for a statement on this matter to try and clear up just how long of a wait is expected.
