One of the major faults of the Wii U launch were the exceedingly slow loading times. We mean... sloooooow. The outcry against them was heard and during January's Nintendo Direct, Iwata himself apologized and promised two updates to address them, one in Spring and one in Summer.
Well, we're fast approaching April, the target for the Spring update. And as April approaches, Nintendo has released a comparison video showing the improvements in load times.
Take a look...
The drop out from New Super Mario Brothers and into the system occurs at the 23 second mark. As you can see, the updated Wii U returns to the system menu 8 seconds later. The launch system, well... it takes a lot longer. Obviously, it's a major improvement.
Along with the load time improvements should come stability improvements as well. And If this isn't fast enough, recall there will be a second update in Summer.
