For me it was seeing the hunters absolutely destroying a team of Spartans, they were swatting back grenades and knocking them around like rag dogs, it just looked next level halo all the way.
What moments have you seen that got you excited? This is a positive thread, plenty of other threads for negative thoughts.
That moment where i haven’t clicked on any campaign footage. 
Just knowing Blue Team is in it got me hyped.
Opening cinematic.
Seeing that master chief is alive and kicking -Yoink-!
Seeing the Halo 5 logo pop up on screen in the opening cintematic with the huge blast of brass in the background. I literally started laughing hysterically in joy
Muse playing and then the break when Buck yells “Contact”…then back to the jam
Both intros for each team. I’ve been watching those a bit too much if I’m being honest.
Buck’s witty commentary to Locke. I’ve been waiting since ODST for more of this.
Basically whenever I see masterchief. <3

I can relate.
When I found out my retail copy will be delivered by 3pm tomorrow
Locke: That’s twice.
Buck: Oh we’re counting now?
When that bass drops

-Yoink-… I kind of envy. I thoroughly enjoyed all the vids I’ve watch but part of me wishes I didn’t watch so I could 100% surprised at every moment. So have you not seen ANYTHING??
OP, that is my favorite moment as well. The Hunters seem to have been improved, which might make for a more interesting challenge. I’ve disliked how easy it was to beatdown Hunters in the previous games minus Halo 2, hopefully they’ve made them a bit more smarter in cqc.
