How long will we have to wait...

Before we can get Anniversary maps without buying CE:A?

And another thing: How long will we have to wait before we can get the no bloom custom gametype?

Thanks!

No bloom custom gametype comes out on the 21st of September.

The maps however will probably come out quite a while after CEA (Like a few months). The same happened with the mythic maps on the Halo 3: ODST disc.
