I dont think people were expecting mainline halo numbers. That Halo 3, Reach, and 4 has all sold 10m+. so i doubt anybody thought it would do that.
Most people were comparing it to Halo Anniversary but said it would sell more which it is going to. While i dont have factual evidence id say most people are predicting 3-5m lifetime. Keyword is lifetime here, not 8 weeks. Itll very likely reach 3m+
But yes the launch woes did hurt it no doubt about it. Its sad that it had those problems. Should teach them to beta test for now on.
However 1.8m is far from dissapointing.
