It all depends on your expectations:
If you regard Little Big Planet as a quality addition to the PS3 library that will see strong (2-3m lifetime) sales, you should be happy. It's right where it should be.
If you're one of the people who has been touting Little Big Planet as Sony's salvation, well, you've got some explaining to do because it did nothing to improve hardware sales.
Expect to see massive spinning and downgrading of LBP expectations from Sony fans over the next few weeks. You can already see it in this thread, actually (e.g. leo-j trying to include sales from three different weeks as "week one").
End of 2008 totals: Wii 42m, 360 24m, PS3 18.5m (made Jan. 4, 2008)
