When does 5 come out?

When does halo 5 come out and what are the best things about it?

Oh and when will they release the beta?

Around holiday season next year, and the Beta will launch December 29th this hear for three weeks.

Halo 5 will probably come out either November 3rd or 10th, but it could also be in September (22nd or 29th). Halo games have only ever come out in late September and early November (with the exception of halo wars) and the above dates are the Tuesdays of those months in 2015.

All speculation of course, but based on history.
