Regions and Accounts:

The Nintendo Switch system is not region locked, but we recommend that players buy games within their region to ensure full service and support. The user will access the Nintendo eShop that corresponds to the country identified in their Nintendo Account. (Up to eight user accounts can be created on a single Nintendo Switch system.)

Cards:

The Nintendo Switch system has 32GB of internal NAND memory, a portion of which is reserved for use by the system. The system’s internal memory can be easily expanded as needed using microSDXC cards.

The SDXC standard supports up to 2TB of storage. (Note that 2TB cards are not yet on the market, but Nintendo Switch will support them when they are.) External USB hard drives are not supported at launch, but we are researching the possibility of supporting them in the future.

If no microSDXC card is used, everything is stored in internal NAND memory. If a microSDXC card is used, game save data is stored in internal NAND memory while data that can be redownloaded, such as digital games, game updates, and DLC, is stored on the microSDXC card. Nintendo Switch game cards are non-writable; game save data is stored in internal NAND memory.

32GB of internal memory? Seriously?
The smartphones running their matchmaking and voice chat will have more space than that lol

what the game cart can't save now that is retarded.

FYI, almost all home console (and vita) save in their internal memory

don't care. i've grown up used to a standard. this s goign backwards for Nintendo.

and to think at the start of the gen i wanted them to implement hybrid cards to tackle the space issue.

64gb cart = 40gb for game 24gb for DLC and patches and save files. how awesome would that be??? no more worried about console internal space.

So, it doesn't allow external hard drives at launch?

Good so far.I really dont see an issue with the non writable cards.I mean, would be nice, but I guess this is to prevent DLC to be written on the cart and sold.(Potentially killing profits from companies from second hand games that would need otherwise to buy DLC)

No, but its possible after.Just microsd so far.

This also means that you can buy japanese games for example by the eshop.That is nice.

Even 3DS cards couldn't save DLC. To enable cards to be overwritten with patches and DLC would require the cards to be rewritable, which would make them way more expensive than the read-only cards Nintendo has been using in their portables.
