when the new system VOD will be available ?
What do you mean by “new system vod”?
I refer to this post : http://blog.twitch.tv/2014/08/important-reminder-past-broadcasts-removed-today/
Nobody knows about that ?
AFAIK, the new deletion policy has been in place since that blog post. VODs being available on more platforms with more redundancy is still being worked on. There is no ETA.
