Both my TRU's have had no combiner figures, though I did come across a Thudnercracker and Windcharger. And I just picked up Windblade though she's technically a Generations figure. They need to get these AOE toys out on clearance.
The AOE figures are part of the problem, I think. Where I am, there are tons of those left along with some FoC Cassette bots and cons and even some Transformers Prime legends and the occasional deluxe figures. If the old stuff is still there, then the new stuff doesn't get distributed. Collectors get tired of waiting or else concerned they'll miss out and buy online. Then by the time we see CW toys, the collectors will already have what they want and then CW will be the new shelf warmers. The cycle starts anew.
