It does look like the flash rotation won't get too far "ahead"...of the last 50 games that appeared + the 5 currently on view as coming soon, 45 were on their 2nd go-around, only 10 already on their third. So it looks like all games will probably be making their second appearance (unless they've been removed from the rotation for some reason) before anything shows up for the 4th time.
With that said, here's what's left for the 2nd rotation:

That's 46 games or about 14 hours worth of flash cycles. Add in a few 3rd-rounders (and the 5 games already listed as coming soon right now) and I'd guess these will all be appearing in the next 18 hours or so.
