Considering the Patrons haven't had a schedule for recordings since November, I wouldn't count on you plebs getting one. LEGO Live being this month will also throw off any schedule that might be generated since they have more important stuff to do than make a PDF of when they're recording. I'd say if there's going to be a schedule open for everyone to see, it won't be available until March, but that's just my guess, I could be completely wrong.
In the past, this is how things have usually worked out, but of course everything is subject to change, so take this schedule going forward with a spoonful of salt:
Wednesdays: NinjaGo Cast at 6 EST or later
Thursdays: Brickfeed at 4 EST or later
Fridays: TTV at 6-6:30 EST or later
Saturdays: Brainstorm at 12:30 EST or later
