Wait this is even more confusing as it is the first time they have released a sequel to the two mainstream pokemon games rather than making a third version or moving on to the next generation.
Pokemon Grey may have seemed a bit weird to release on a new platform, but these sequels could have been very easily been released on the 3DS, it would have made too much sense. Well whatever, I was going to buy the 3DS with the new pokemon 3DS, but now this saves me some money as I can just get it for the DS.
