Halo 4???

[Flab-Ender]

The awesome story is still there, you're right. But.. and it's a big but; Halo is now hanging in the balance in terms of how good their next main title will be, meaning Halo 4 (if there is a fourth..)
It can easily fail so hard, because the avid fan will be expecting an absolute epic ending, and Bungie have to deliver perfection, if they're to make Halo 4.

If I was Bungie, and I decided to start development on Halo 4, I would be crapping my pants due to the pressure!

I say, what do they have to lose? They've made millions already. Especially if they just make a download.
