I was watching this one (it juuust finished) and they apparently had one yesterday, which I magnificently missed. D: There's no timeshift either, sob.
Yesterday's gate: http://live.nicovideo.jp/gate/lv49418906 (useless link - i just like to sadface at it, lol)

But apparently, they'll said they'll be having another one tomorrow. Which I don't have a link for the gate (I'm sorry for being useless! ; v;), but I thought I'd let you know anyway...
