Technically, that's not true anymore. DST/AA products are now showing up at Toys R Us.
They are now, yes, but it seems to be in rather limited numbers. (I got a phaser the other day.) They had six to eight pegs, I think. They also got Enterprise product into TRU, and Borg figures and the original Minimates into Target years ago, but that stuff didn't sell so hot. I think they've been taking baby steps as a toy company to recover from that. (As a design house, they're stuff is as good as ever and in some cases better.) But I don't think the could get six feet of shelving at TRU the way Hasbro can with Star Wars, Clone Wars, and Indiana Jones (even if the Jones toys were a flop).
