I agree with you but I also want to add a few things.

Players did ask questions in regards to open world content, open world grinding for exp so forth and so on but it seems that Yoshi didnt answer the tough questions or refused to answer for whatever reason (unless theres more to come on that).

Things that worried me and I am sure a lot of other players is that it seems as though the open world will be nothing but eye candy or kinda like just a lobby. No open world grinding that would be very efficient and that players will be forced to quest or run dungeons to gain their exp (again not all players want to quest or run dungeons for exp).

HNM's that are open world so others can watch other players win or lose, it seems everything will be instanced to the point that players will be hand held all the way to cap with very little choice.

Summoner or arcanist will get 1 summons only (with the possiblity of getting more later), but we already have an answer to this question and all we have to do is look at FFXI as it took them years to add more summons if you will.

The fact is SE didnt learn from their mistakes in the past and continue to make the same mistakes, but the big question will be: At what cost to them (SE). Only time will tell and alpha and beta will answer alot of questions that Yoshi either cant answer or out right refuses to answer. If 2.0 dosent cater to all player bases, if the UI and evrything else isnt up to par than this may well be the 1st Final Fantasy title to fail, not to mention SE will never recover the amount of money they spent making 1.0 or 2.0.
