Wedbush Morgan Securities’ analyst Michael Pachter has predicted that the Wii’s lasting bout of momentum will last until Sony drops the price of its PlayStation 3 down to $300. He further believes that 2008 is “definitely” Sony’s year, with hits like Grand Theft Auto IV and exclusives such as Gran Turismo 5 Prologue.

I think the Wii momentum will last until the Playstation 3 is under $300, so another year [...] 2008 is definitely Sony’s year. And I’d throw Grand Theft Auto IV into the mix, given that it’s considered a PS2 owner’s [franchise]. Also, Gran Turismo 5 Prologue should sell some consoles…
