Some of the things I've seen have been good and the Beta was sort of fun, but it was too heavily focused on the Lockout/Midship/Arena gameplay and not enough traditional Slayer. We also never got to try any Covenant weapons or ANY vehicles.

War Zone looks interesting, but I feel like it'll be similar to Invasion in that it'll be popular at launch but matchmaking times will grow as players lose interest and trying to cram 24-people into a single match when MCC can barely handle 4-v-4 makes me doubtful of it's future.

REQ packs and the whole concept of an in-game "buy your DMR" stuff similar to Halo 4 has left a sour taste in my mouth and the possibility of less armor customization is really off-putting.

We've also seen next to nothing for Forge, Customs, or Theater.

Those are the three biggest modes for me and until I see something concrete or uniquely interesting about any of them, I am not preordering. Not to mention the whole Preordering-in-general bullshit and unpolished game releases because of it.

I'll pick up Halo 5 Day One, but I am not preordering any games unless I am overwhelmingly convinced to do so and only Fallout 4 has even had a glimmer of hope in that regard... :\
