Sorry but you seem to be clueless.
Nintendo don't see any of the additional profits that retailers make when they mark something up higher than RRP. The retailers are already making a profit based on RRP (otherwise what incentive would they have to even stock it in the first place?) and you can be sure that the buy-price for retailers isn't the same as the RRP, it'll be less - maybe only tens of pounds per console but this will rise with the scale of the buy order, etc.
The RRP is simply a guide price advisory given by Nintendo. They get their money (including a profit on the manufacturing costs, etc) regardless of what the retailer sell it at. For one thing Nintendo can't assume anything about the running costs of a given retailer so it couldn't make a sweeping judgement about one pricing it higher than another.
If you think that Nintendo, or any company, have any involvement in shopfloor pricing outside of setting a RRP then you really are clueless.
If I'm so clueless (lol), then please explain to me why Valve (Steam) raised the price it sold CoD4 at to UK customers? Was Valve just profiteering from shortages of bandwidth in the UK lol? Or could it be, like I've been saying all along, that retailers have to sell at the price they are told to by manufacturers - in this case Activision, or they don't get to sell it at all
