Demo to hit ahead of Hounds?

Nothing like an un-sourced German gaming site rumor to get your demo date hopes up:

SEGA gave some new info about [Chromehounds] today!

30/06 a theme pack and the demo will be downloadable from marketplace

11/07 a second theme pack will be available.

15/07 part pack 1 will be on the marketplace

15/08 part pack 2

15/09 part pack 3

Sounds good!!!!!!

I read the news on various German game sites, so a link wouldn´t be useful I suppose...

I played Chromehounds at E3 and found it to be pretty generic stuff, but I'd still like to see the demo (with multiplayer) released before the disc hits stores on the 11th of July. Unfortunately, June 30 is a Friday, and we all know MS doesn't release new stuff on Fridays. I'd start hoping for July 3, but a holiday week doesn't sound like a safe bet either.
