I really hope so, too! And I think there’s at least a good chance. As you say, Drift and Windblade have already appeared in other media, and the IDW books are a great source of compelling original characters that I think Hasbro would be foolish not to tap into further. For those who aren’t quite as well known or aren’t as easy to fit into your typical heroic Autobot team (like Pharma or Trepan, say), it might take a little longer, but I’m confident we’ll see some of them (I hope all of them!) before too long. I’m firmly of the belief that nothing really dies out in Transformers. Hell, look at characters like Rattrap or Knock Out and Breakdown popping up in IDW!
I’d love to see everyone on your list make an appearance in other media, and would also love for Rung, Tarn, the DJD, the Necrobot, the Scavengers, and many others to carry over. (I realise the revelations towards the end of Lost Light might make Rung a little difficult, but still. :))
And I suspect we’ll also see more IDW takes on existing characters, especially those who were less well known before. Like, Tailgate in TFP was a wisecracking soldier (what little we saw of him), but I’d be surprised if Tailgate showed up in future media and wasn’t, you know, adorable waste disposal marshmallow with a penchant for broody jets. 🙂
