Where there were rumors there are now facts: the DS lite will be launching in Europe on the 23rd of June for £99.99/149.99 EUR. As a way of compensating people for the extra two week wait over the North American launch, the European DS lite will be available in black at launch. However, I'm sure the majority of potential European DS lite customers would forego this novelty in exchange for some price equality: Europeans will pay the equivalent of $191 for the DS lite whilst Britons will pay $187. Compare that to how much Americans will be paying on the 11th of June: $129.
