Corrinne Yu Engine Programmer of Halo 4 said

on twitter that its Halo 5

Still strange how the teaser didn’t say Halo 5.

Or even why this forum says Halo Xbox One instead of Halo 5.

Maybe they thought we’d have common sense to kmow?

Even if they still go with the title “Halo 5” not mentioning it is smart because they retain the option of choosing a different name if they come up with one.

Linky to the tweet

It was obvious it was Halo 5. Cortana’s gone and Jonh’s visor has a crack on it. Both of which come after the events of Halo 4.

People who didn’t think it was Halo 5 most likely didn’t want to believe it was since Halo 4 was just released.

Still, it is odd that 343 chose to just call it “Halo” during the reveal.

She simply clicked “Share” on the YouTube video. The Tweet has the exact text formatting of the YouTube video title. Don’t take this one as confirmation.

I’ve seen tweets from the official xbox twitter handle calling it halo 5.

Maybe they are working on the title…maybe it won’t be called Halo 5 since frankly the numbers are getting a tad old. Halo:Meheco?
