So, I can not help but feel partially responsible for this, so, let's drop some clarification.
1. My Primeval Whirl might be closing in a year or two comment was reffering to a different proposal for Dino
2. This proposal (as I believe Martin has stated) is in the very early consideration stage, and wouldnt happen until post-2023, if at all.
3. Just because Indy is being vaguely considered for AK, that doesn't stop other things from being considered for AK, or Indy from being considered elsewhere.
4. It is near impossible to turn Dino into an exact clone of either Indy.
5. Dinos should be here during the 50th.
