Who is really optimistic about this game?

This would be a great start indeed. The first things Wada and Yoshida said with the team change is that they plan on regaining customer trust and communicating more. Posting the same old "we can't do X" or "we're looking into X" or "I will bring X to the devs" is a non-response. It's only one step above being completely quiet.

And giving detailed responses is only one step below "lying". Half the people here have no clue as to what they mean by "assessing costs" and "algorithms". Going into programming specifics woukd be dumb. Either way, nobody is going to give a shit about their early communication if they fix the damn game. Your priorities are all kinds of fucked up if you think they "should" focus on letting us know every single concept, problems in implementation and testing as well as all the setbacks that make the feature less than intended.

"We can't do X" is not a non-response. You may not like it, but it answers your question very clearly. You don't like the answer? That doesn't make it a non-response I'm afraid.

The letters from the producer were a great series, but they need to be way more detailed. We need status of what's holding up development so much, with a very detailed analysis (hint hint, tell us what this "core programming issue" is). We need to know what their exact thoughts are on fixing X or Y, even if the solutions are not correct or what we need (so that we may tell them otherwise). A big chunk of the player polls from the beginning of the year have seen no sort of follow-up.

We don't "need" to know anything.
