I honestly think the marketing for the 2DS here in the UK has been absolutely disastrous. It's played on the radio CONSTANTLY during the day, but jumps from 3DS XL, to DS, to 2DS playing 3DS with 3D, to 'all part of the 3DS family' and I just saw my work colleagues all looking completely bemused.
What a f*cking disaster. Everyone thought it would sell because of Pokémon. Nonsense. 3DS XL would sell well with Pokémon, no problem. 2DS looks cheap, feels cumbersome, loses the major point of 3DS games (yes, I believe the 3D adds to the experience!), and is far more prone to breaking/scratching because it doesn't close like before. 3DS XL was amazing...2DS is horrible, and any advertising so far has confused consumers considerably, from what I've witnessed.
