Can we download the new maps for Halo 3 separately from Halo Wars yet?

[Old Gamer 56]

I'm not interested in the RTS game Halo Wars, but I am very interested in the new maps for Halo 3 that were included with Halo Wars. I read somewhere that you could purchase and download them separately soon after the release of Halo Wars. Can we do that yet? Also, does anyone know if these new maps are for Slayer? Thanks

The Mythic Map Pack will come out on the Xbox Live Marketplace some time around June for 800 Microsoft Points. You could also wait for the Halo 3: ODST Expansion Pack to come out in Christmas 2009 which will include the Heroic, Legendary, and Mythic Map Packs as well as 3 new maps: Longshore, Citadel and Heretic.
