I think I will wait for 1st week US numbers (should be soon), and first week EU numbers (next week) before I make any assumptions on sales.
Nobody expected Mario Kart or Halo sales first week.
I assume people were referring to LBPs lifetime sales and ability to sell PS3s to casual gamers who did not own a PS3 as of yet. You will have to wait through the holidays to see if it was HUGE or not so huge.
