Have you noticed the CE symbol on the back of the Nintendo Switch? Perhaps you have, but what's the big deal about it? Well if you look at other consoles from an non-EU region, you'll see that the CE logo isn't there. That's because the device isn't intended to be sold in the European markets. On the flip side, most phones have both the FCC and CE logo on them, since we usually have one model of phone meant for sale in all regions.
This is just speculation right now, but that logo could certainly be the best indicator yet that the system is region free. The one major thing that flies in the face of that speculation is the DS. The DS lacked a CE logo, but as you well know, it was a region-free device. Let's hope we find out what's up with this aspect of the Switch on Jan. 12th.
