Milage sale anytime soon

I'm just about to book some redemption flights.. but then thought.. hmmmm, isn't it around this time of year that there's normally a milage redemption sale. Anyone know if we're due one soon at all?

My notebook says the previous reward seat sales were in Jan, May/June and then late August/September time.

Yep, my record says the same. I'm expecting one in September where I am hoping to use my pe vouchers.
