Rather than just yelling doom, or that there aren't enough Wii Us being sold, it might be beneficial to actually look at what was modified in the modified forecast.
Wii U hardware sales are still forecasted at exactly the same as they were before, and the Wii U Software is forecasted to be 40 million higher than in the previous forecast. Clearly, a lack of games on the Wii U is not the reason for the lowered forecast.
The 3DS is modified somewhat downwards, with both software and hardware sales being roughly 1/6th lower than previously forecast.
I'd also like to point out that the OP's claim that the revenue is slashed by half is incorrect. Net sales - which is more or less revenue - is 15% down from the previous forecast, and 10% down from last year.
Their forecast operating income is down from the previously forecast operating income, but up from last year's.
The only thing that's taken a huge plunge is the ordinary income, and that's happened largely because of the exchange rate. There's no "Trying to blame it on exchange rates when it's really that they're just not releasing games this year", because the reason for the large drop in ordinary income isn't lower revenues.
ZhugeEx has this completely correct.
