Seems kinda low.
3DS at $250 shipped 3.61 million launching in Japan in late Feburary and US/Europe in the last week of March. Keep in mind though Japan had that monstrous earthquake right after the 3DS launched, so supply was cut off, but I think they were hoping to ship 4 million.
2 million if it's worldwide means like 660k for Japan, North/Central/South America, and Europe/Australia a piece ... or someone is getting the shaft with supply (I'm guessing Europe).
Nintendo might be gun shy because of poor 3DS and Wii U launches, not wanting to get stuck with unsold inventory. March is also not the Christmas holiday season, so they don't have the same leeway of a seasonal shopping boost.
