[DroidKnight]

Sales by VGChartz numbers in millions

Halo Combat Evolved   6.43

Halo 2   8.49

Halo 3   12.13

Halo 3: ODST   6.3

Halo Reach   9.97

Halo 4   9.96

Halo 5: Guardians   4.92 (Online searches show more)

I wanted to get this out before Microsoft starts showing any gameplay.  With the launch of Microsoft's new Xbox Series consoles happening in about 5 months, it was confirmed that Halo would once again be brought out to accommodate a console launch which has only occurred once before with Halo Combat Evolved in 2001 with the launch of the first Xbox.  Halo 3 is the best selling game in the series and considered to be one of the greatest games of all times.

Following the acquisition of the franchise by 343 Industries sales took decline for Halo 4 and 5. By how much of decline is hard to tell with Halo 5 sales numbers hard to acquire.  Some searches show Halo 5 sales numbers quite a bit higher than VGChartz but without confirmation who's to say.  Here is an entry in the Halo 5 Wikipedia page, anecdotal only.  (In a Q&A session, in May 2017, between Michael Pachter and his audience, the gaming analyst recounted his conversation with Microsoft regarding the success of Halo 5. Contrary to popular belief, the analyst says that Microsoft told him that the title sold “on par” with games like Halo: Combat Evolved, Halo 2, Halo 3 and Halo 4. This suggests that Halo 5 had sold at least 10 million units.)

Five years have passed since the development of the last Halo which is the longest time between Halos.  Microsoft has got to be wanting to make this their flagship game once again and appear to be doing everything they need to, to make it so.  I don't think this is going to be just another game in the series, it's going to be Halo reimagined.  This will be a longterm supported project and will bring back past Halo players, retain current ones, and open the genre to new ones.  

With a huge PC player base, 47 plus million Xbox player base, launch title for Xbox Series X, this game is going to sell great.  My prediction is Halo Infinite will sale over 22 million units lifetime.  This will be the best selling Halo.
