Selling like hot cakes?

The answer is "not particularly."

Nintendo responded to Sony's Playstation 3 outselling the Wii by just under 50,000 units in Japan in March by saying "it is still the first few months of the year when sales are slow for the industry" and that the plan of action is "to line up strong software to support hardware sales in the second half of the year."

7.8 million Wiis and 2.7 million PS3s have been sold as of December 2008 in Japan, with the PS3 having a one month head-start back in November of 2006. The reason for the sales surge seems to be demand for key titles such as Resident Evil 5, which isn't available on Nintendo's machine.
