Nintendo Switch accessories are already being listed at EB Games Australia, with 3 products up for purchase so far. These include a Starter Pack and Starter Pack Plus accessories, and an “Extra-Long 3m Charging Cable.”
The Starter Pack and Starter Pack Plus listings include mention of a Go Case, screen protectors, and cleaning cloth. The plus pack also lists earbuds as well. The final listing is a USB-A to USB-C charging cable measuring at 3m. USB-C is a newer type of connector that allows faster chargin, and this could be an indication that this is what the Switch will use, but we have no confirmation yet.
