Eurogamer: "What's great news for consumers, though, is precisely the opposite for Nintendo. In some regards, the launch of the 3DS seems to have been engineered to avoid the massive shortages which we witnessed with previous hardware launches - most notably the Wii. The firm dropped the console into the market in spring, rather than autumn, far away from traditional times for mass market gaming purchases. If that was the strategy, however, it's unlikely that the firm expected - or wanted - success on quite this scale.
Bluntly, the excitement around the 3DS has fizzled out - with the first wave of early adopters driving a sales spike, only to discover that there's not much in the way of a second wave waiting behind them. The most worrying figures come from Japan, the market in which the DS launched first. Here, we can see a clear spike followed by an incredibly rapid fall in sales, to the extent that the 3DS now lags the PSP in week on week sales."
