It does seem odd that it'll run out of steam just as we're likely to see season two appear, but given the short lifespan of comics these days I wouldn't be surprised if they knew from the start it would be a six issue run and that's all they're intending it to be. There isn't anywhere else they can take it without either stumping up for original content or changing the target audience to older kids for the other IDW books.
Just another week before we get close to seeing UK #5. But they don't really have a news section in the comic or anything online to give us a clue to what they are doing. But I just read IDW #0,1 last night & if you see clues in the story going back to TF#1. Decepticon attck & Autobot is taken back for repairs by the group of humans we are introduced to.
It does seem ironic that so many Transformers toys (ie for children) are now based on comic designs from IDW issues which often, er, aren't suitable for children.
Yes, it is rather unfortunate. I miss that strand of kid-friendly action-adventure comic into which the original Transformers comic, GI Joe, Action Force etc fitted. There doesn't seem to be that same point on the scale these days.
