That's true, I am just making assumptions. I'm just seeing first hand and through the sightings here, a greater turnover of Generations toys than AA/Movie toys, since the Movie 'Season' ended. It just suggests to me that Generations can sell without a movie (or any visual medium) selling it, but the Movie toys can't. But without sales figures from retailers (not Hasbro*), I can't say for sure this is true, or why.

* Hasbro figures would be biased towards the Movie line, because that's the line they pushed to stores to pre-order in greater quantities at Toyfair (and as such, imported more Movie stock). Kinda like how Music artists are awarded Gold and Platinum records based on sales to retailers, not to customers.
Since we've seen greater turnover of Generations figures in stores, to the point that stores run out and are slow to restock (they know they are scheduled to receive more pre-ordered Movie toys to add to the ones still warming their shelves, and Hasbro are more likely to run out of Generations figures because stores didn't pre-order as many at Toyfair), I'm just guessing that just like during the time of Beast Machines, Hasbro have looked at why certain toys/lines aren't selling and changing things to compensate.
