Even the most hardcore fanboy can admit that the 360 has lost some steam in the past few months but I know one way that they would be able to easily leave PS3 in the dust and even give the Wii a good battle:
Drop the price to $200.
With the falling price of hardware I think this could be possible.
Let me ask you this: If you could choose between a Wii for $200 or a 360 for $200 which would you choose?
Even for me this would be a tough choice. I'd go with a Wii but only because I have a PS3 and a gaming PC but still..... That would be a tough choice.
