“I believe the Wii will continue strong growth although supply continues to be a problem,” said Billy Pidgeon, video game analyst, IDC. “I’d like to see Wii hardware shipping in larger quantities or mass market consumers may cool on it. Having said that, I don’t believe supply will meet demand for the Wii until 2009.”
On top of that, many are still predicting the PS2 will continue to thrive, well above the PS3. Particularly due to a lack of selection on the PS3 and Xbox 360 and lack of interest in hi-def consoles, the older console has a lot going for it (aside from price). On the Wii side, Nintendo hasn't mentioned if they plan to expand manufacturing, though it would clearly be to their benefit. If sales do continue to perform as they have for the next year and a half, the Wii wll have ascended far beyond Sony's claim of it being an “impulse buy”.
