The next-generation is finally here with the Nintendo Wii U launching yesterday in the United States, but with this great change comes unexpected technical difficulties.

Early reports are that some are experiencing very slow loading times, while other Nintendo fans are reporting system freezes and crashes.

Nintendo released a statement about the issues, and urged customers to phone their customer service line should they experience any more problems.

“We are aware that users are experiencing load times when they launch or switch between applications," Nintendo said.

"We are exploring ways to enhance features for consumers’ overall experience.”

Troubles aside, the first next-generation console in the world has exploded onto the scene, selling out entirely and sparking absolutely mad rushes to get hold of one.

Listings on Ebay.com go as high as $750 USD for the console, well above the retail price of between $300 and $350.

The price might seem ridiculous, but desperate gamers will sometimes do ridiculous things; the original Wii got a similar reaction in 2006, selling online for more than $1000 – four times the retail price.

Bill Trinen, director of product marketing at Nintendo, told Gamespot.com they would try to produce the consoles as fast as possible to meet demand.

“As we did with the Wii, we’re trying to manufacture them as fast as we can and bring them to market as fast as we can so we don’t have any shortages," he said.

"But, back on the Wii, I think the volume for that system was unprecedented. So it’s tough to use that as a barometer.”

The next-generation was always going to come with a few speed-bumps, so we’d like to hear from you guys.
