The $200doesn't arrive in stores until Sept. 20. But the updated version of the larger, more versatile $300 is now available in some stores in the US. The for longer playtimes, but is otherwise identical to its predecessor.
CNET and GameSpot staffers in Los Angeles, San Francisco and New York were able to buy the new Switch at GameStop/ThinkGeek and Target stores over the past 48 hours, and we'd expect it to be widely available at nearly every store that stocks Nintendo gear in the near future. For now, you're better off looking for it at brick and mortar stores, where you can by its red box, as seen above, and a distinguishing serial number. The older model has a white box.
If you're an existing Switch owner interested in trading up to the new model, GameStop looks to be your best bet: You can walk away with a new Switch for just $75 plus tax, after a $225 credit for your old model. Just be sure to budget some time (and patience) for doing an in-store data transfer. Nintendo has hinted that process could be improved by the time the Switch Lite hits next month.
We'll have hands-on impressions of the new Switch's battery life and the data transfer process in the near future.
