it's not doing poorly, it's in it's best year sales-wise
Compared to a similar time-frame last year (6th of Jan '07 -> 21th of July '07 against 5th of Jan '08 -> 19th of July '08)) it managed to increase it's sales by ~51% (2.46M vs 3.71M) according to VGChartz
it's just, that the other consoles had a larger increase, which obviously is because it's their 2nd year, while the 360 is in it's 3rd year
edit: I just realized, that the hardware numbers for the week ending the 19th of July '08 aren't complete yet, so the sales increase of the 360 should be even a bit better
