If you combine when the D40x was introduced with the D40, it looks like they've collectively been out about as long as the D50 was before it was replaced by the D40 (Wikipedia being my source). I'm saving up for a D40 right now but does anybody think it's about to be replaced or even discontinued and just go forward with the D40x for now? Other than the timetable I laid out above, the price on Amazon for the D40 has kept dropping recently, now down to $498.
