Honestly i see SONY and Microsoft in the same situation when it comes to price cuts, and both will probably do $50 price cuts on all there models hoping to keep sales flat this year.
Nintendo on the other hand is in an awkward situation -- any price cut really needs to be at the end of the year and then they are still likely to end up down YoY ~20% with a price cut. Nintendo need something new to keep the Wii selling well and distractions with the 3DS won't help.
