People tend to see stuff like that as motivated purely to drive toy sales, since it means an entirely new line of toys kids have to collect. And admittedly, in cases like this (especially when Hasbro is involved), it's usually not far off the mark--creativity and production values suffer for the sake of selling more toys. Some companies are so notorious for this, it's created a sort of "rant first, judge later" mentality in fans.
Since I don't really collect tons of toys, I'm willing to wait to see how this pans out to make any judgments (if it's true at all). The idea isn't bad in and of itself, but a lot just depends on how they treat it--as a production worthy of the time and money needed to make it good, or as a glorified toy commercial.
