Thats your opinion, and I doubt anyone would get you to change that. I don't want to, either. But Halo 4 would be on the same road as COD. MW3 is pretty much MW2, but a couple changes, such as Theatre, new Campaign, etc. That would be the same with Halo. I respect Bungie for taking their time with games, and not making a complete new one every year. 2010, Halo: Reach was released. One year later, Anniversary was released. One year after that, Halo 4 will be released. The reason for so many games in the past year is
A. Before Reach, I was awaiting a new game. It has been three years.
B. 2011 was ten year mark for Halo. A remake of Halo: Combat Evolved seemed pretty reasonable.
C. 343i has worked on Halo 4 for many years. If they are nearly finished, why not announce another Halo?
Anyways, I couldn't go back to Halo without Sprint. It makes such a better gameplay experience. Jet-pack is so much fun and useful, even though I don't normally use it for Matchmaking. Hologram was a huge success. Active Camo is perfect. Armor Lock is helpful, but can be a real pain, which is why it shouldn't be able to destroy vehicles.
Face it, the majority of people like it better now, and 343i know.
