Not that they go into any great detail about the GPU/CPU, or any detail really, but they provide a detailed description on the unit itself, battery life, and connectivity capabilities. And confirmation that a percentage of the 32Gb of internal Nintendo Switch storage will be utilised by the system. Making memory expansion just about a necessity if you plan on downloading anything digital for the system.

Cue, the specs.

Battery life
Battery life can last for more than six hours, but will vary depending on the software and usage conditions.
For example, The Legend of Zelda: Breath of the Wild can be played for roughly three hours on a single charge.

Charging time
3 hours approx.
Please note: this is the time taken to charge while the console is in sleep mode.

As per the note under the microSD slot specifications, a day-one firmware update for the Nintendo Switch is just about confirmed. But then again, that's par for the course for any game or hardware release these days. Perhaps the biggest cause for concern is the battery life and the charge times, which don't seem all that great compared to other Nintendo handhelds.
