Regardless, it's pretty obvious that Nintendo is charging $250 for their new device because that's what early adopters are willing to pay for it. Expect the MSRP to adjust accordingly to consumer demand.
This is not "price gouging." Price gouging is when retailers force consumers to purchase bundles or people flip products on the secondary market well above MSRP.
If nothing else, the pricing should ensure that supply constraints won't plague the platform for years as was the case with the Wii. They have learned from their mistake which may have been well over a $1 billion loss in revenue that could have generated had they priced the Wii higher than $250 for the first year or two of availability.
You can always go down in price. Raising the price on the same product with the same features due to initial underpricing on the other hand... not so much. At best you can re-release an updated product with additional features for a slight premium (DSi, DSXl).
