The house that Mario built's always been a step behind the curve, but no more. After a dramatic price cut to the four-month-old 3DS, Nintendo's revealed its plans to offer downloadable content (DLC) and micro transactions through its eShop for the glasses-free handheld and the upcoming Wii U console.

The gaming war in the handheld space is about to get really ugly. Nintendo might have successfully launched its new glasses-free 3DS handheld in the U.S. to the tune of "best U.S. launch day sales records," but what about Sony's encroaching NGP, Apple's delectable iOS devices or Android? Is old Nintendo concerned?

Nintendo held two special press conferences focused on its upcoming 3DS handheld today, one in New York City for North America and one in Europe. Here's a round-up of everything Nintendo announced, including when the 3DS will hit store shelves to how much it'll cost. How many games will be available at launch and what's new about those pesky Friend Codes? Plus some old school handhelds return thanks to the Virtual Console. Find it all and more below.
