$170? Sons of bitches. I saw that Amazon price earlier today and thought seriously about it, but with the Zelda delay I've got nothing else to grab for Christmas so I'll probably gift it and then hopefully pick up some games cheap on Boxing Day[/wishful thinking].
$150 is really quite tempting, although if you were at all interested in Mario I'd take the chance of seeing if some idiot salesperson might sell you a bundle for $170.
