When Nintendo of Japan's Satoru Iwata recently sat down with the Wall Street Journal, he let it be known that Nintendo would have four million 3DS systems available to consumers worldwide through the end of the fiscal year on March 31.

Of these four million units, 1.5 million will be allocated to Japan with the remaining 2.5 million systems left over for distribution throughout North American and European markets. What this means is that if you want to be guaranteed a system on launch day, a pre-order wouldn't be a bad idea.

We'll keep you posted on any further 3DS information as it becomes available, and don't forget the Nintendo Media Event coming up on the 19th where we should see a hefty dose of new information on the system and its upcoming March launch.
