Sony Computer Entertainment of America spokesperson Dave Karraker says Wii should not be directly compared to PS3. Interviewed by The New York Times today he said, “Wii could be considered an impulse buy more than anything else.†Karraker added that Sony is selling out of the 100,000 PS3 units it is shipping into the US every wek. But, he added, “The frenzy we saw at the holidays has subsided a bit.†Sony believes Wii is currently selling to casual gamers rather than committed gamers, who are likely to buy more games in the years ahead. Meanwhile, Nintendo says its shipments of Wii into the US are equal to Sony’s and has described reports that Wii shortages are down to lower shipments as “absolutely inaccurateâ€.
