The Wii U is probably about 2 months from selling through it's shipment from the end of 2012 (assuming 90% of the Americas shipment went to the US). In Japan, sell through at the end of the quarter is about 20k above shipments at the end of December, and the situation in Europe is likely worse than both. They have basically no chance of meeting the 940k they need to reach their forecast. The only possibility is if they somehow convinced retailers to purchase tons of the new bundles they've put out. There is also a good chance they won't meet their initial forecast of 5.5 million until the quarter ending December 2013.
Kind of funny that there were people claiming shortages last year when there were probably systems on store shelves then that will still be there half a year after launch.
