It is problematic across the board. Even though summer usually sucks, these are extremely low numbers even for first year consoles.
In the quarter between March 31st and June 30th in their first year, the:
Wii shipped/sold approx. 285000/week
360 approx. 150000/week and
PS3 approx. 60000/week (source vgsales so they are not exact).
That´s an average of 495000/week, just for comparison.
