From the latest pre-order article:
"Halo: The Master Chief Collection (XOne) added 48,480 pre-orders for a grand total of 346,452. Expect first week sales in the USA at retail to be in the 500,000 to 800,000 unit range. Expect the game to sell between three million units and five million units lifetime in the US at retail."
Seems way too low. FW sales in the US should be 1m+ for sure...should be around the same as CoD:AW. For comparison, here's some other Xbone games FW USA sales:
CoD:AW (Xbone) - 1,293,397
Destiny (Xbone) - 746,613
Titanfall - 580,521
Watchdogs (Xbone) - 440,488
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
