I actually think that it's important that Halo map packs become "themed" based on map sizes as long as they remain 3 maps per pack, which we already know is the case for at least 3 packs for H4.
Now, this is admittedly based on a small sample of information I've gathered from real life friends, but I think Halo map packs being one of each type of map is a problem with map pack adoption for Halo. Unlike many other games, Halo as a significantly different player count for BTB or regular 4v4, so obviously different maps are required for each. A significant number of players do not regularly play both of those modes. This creates a problem with map packs, as player that primarily plays 4v4 sees the map pack as $10 for the 4v4 maps in the pack. People that I play Halo with outside of GAF are like this, and none of them bought the Noble pack because they saw it as $10 for Anchor 9, which they didn't see as worth it. The same principles applied to the next pack, as they don't play Firefight much, so they saw it as 2 MP maps, and then they never play BTB, so they saw it as $10 for Condemned. The same players bought the Anniversary pack because it included 4 maps that are commonly played on 4v4.
Now, as long as packs stay 3 maps, I think that themed packs will help solve this issue. If one pack is 3 small team maps, people that play that primarily are going to be more inclined to purchase that pack, as it will be a better value to them personally. Same thing applies for BTB. This would hopefully help the DLC issue in MM as well.
The core of the game will be like CE, they said. What happened? :/
