Nintendo thinks 4 million 3DS will sell in a month, and 15 million games.

4 million systems maybe, but 15 million games? No way, not going to happen, that's almost 4 games per system in one month. Besides i wouldn't be suprised if the 3DS gets hacked and pirated in one month.

As already noted, keep in mind that this is shipped...not sold to consumers.  It doens't matter if they buy 1, 4, 10 or 0...so long as those 15 million are bought by retailers.

As for security, apparently it's pretty damn high tech.   THQ was so impressed with it that they agreed with Nintendo when they called it foolproof and so sophisticated that it's hard to describe in laymans terms.
