No DLC Plans For Halo 3: ODST And No Talk On Halo Reach Yet

Bungie's Brian Jarrard has said the developer is keeping schtum on talk about Halo: Reach until after Halo 3: ODST releases in a few weeks:

“Obviously right now what we’re excited about is the impending launch of ODST, so we don’t want to totally start talking about next year’s model before this one’s even off the assembly line."

“But there is a beta that’s coming next year, so all you’ve got to do is sit tight. If you want to be part of Reach from the very beginning then you want to make sure you keep an ODST disc handy."

Senior designer on Halo 3: ODST, Lars Bakken also confirmed there's no plans for downloadable content at the moment.
