Sarcastic Gamer reports:
"At some point you'll just have to trust us on some of this stuff. We have to protect our sources to keep them from being fragged by their employers or associates.
A very good and anonymous source tells us that Halo 4 is already in full development over at Bungie. I wish to God She/He/It had more details to share but at this point all She/He/It can confirm for sure is that Halo 4 is an official project being developed by Bungie, at this very moment.
With more than 20 million copies of Halo 3 sold worldwide, I know it's a no-brainer that the series would continue somehow. It's nice to get this sort of reassurance from a source who has never been wrong for us before.
If we get more details, we'll share them. If She/He/It is wrong… They'll be quietly disposed of..."
The story claims 20million copies of Halo 3 were sold which is obviously incorrect. It is most likely a typo that is meant to refer to the entire Halo franchise or may even be a poor attempt at humour?!
