Current streaming schedule (all times in CET (GMT+1)):
Saturday: Solo tier 1 through 8 raid instances, along with a few tier 9-10 bosses
11:00 am until done, likely with a 30 minute dinner break at some point.
In Mists of Pandaria the streaming schedule will expand to also include the raids in my guild. I might, however, not stream right away at release, as I would prefer to FRAPS our first kills on heroic in order to achieve the highest possible quality for Youtube, and I'm afraid I would get terrible framerates if I am both streaming and FRAPSing at the same time.
