I think it's time to re-examine the expected impact of researching unchained TR150.
- How much faster can Hazō research it now that he has DotB?
- Does Itachi showing up in Leaf shorten our expected time window to find something game-changing? Does going missing lengthen it instead?
Arguably, Itachi showing up means that Akatsuki is not about to open the rift, since he wouldn't need to check that Hazō is not researching it if he thought he had already won the race… Or is this just a pretext for Itachi to do something else in Leaf, right before Akatsuki makes a big move on the rift? This possibility is concerning, now that I think about it…
A lot of "can maybe do" runes are worth second thoughts with DotB, but if we decide TR150 has become worth it, then it should take priority.
(Sorry for the double post. I don't know what the policy is on this. I'd rather not edit in a completely new topic.)
