Further to earlier statements that the Nintendo Switch would only be compatible with 256 Gigabyte Micro SDXC, Nintendo has now revealed to Game Informer that the Nintendo Switch is in-fact compatible with Micro SDXD Cards up to 2tb of memory.
Nintendo are definitely future proofing the Switch as 2tb Micro SD cards aren’t readily available to consumers yet. In-fact, 1TB aren’t readily available yet either. 512gb are available for around $300 which is still quite expensive.
Nintendo has said that they plan to bring Hard-drive support to the Nintendo Switch some point but this functionality will definitely not be available at launch.
