Looks awesome to me. I love that they show a "battle scene" that looks fairly dynamic (your ship getting blown up, you then go on foot and kick ass).. I'm hoping they really focused on battle "Scenarios" in this Halo, it's what really was at the core of what made CE so awesome. Coming upon a battle already happening between the Flood and the whatever the other aliens are, 100 different ways to approach what you do in that battle.. you could wait it out and have less enemies to fight, you could go beast mode and take everyone on, do a bit of both, etc.
I'll probably wait for co-op; honestly my biggest issue with co-op being late, isn't that.. it's late.. it's that it hints to me they didn't put focus on co-op.. that's what partly made CE so great. The game was actually meant to be played with 2 people who might be on the clear other side of a huge battlefield from each other.
Halo CE's roots as an RTS really are what made it shine as an FPS, and I feel like they fairly quickly lost track of that in the series, but it was still always fun, just never "great" to me.
