I must say I LOVE the current build - it seems less buggy, more balanced and more fun than the previous ones, and is keeping me occupied well beyond my allotable time to play...
I do, however, have to submit my own buglist and wishlist, which IMHO would bring the game that much closer to perfection and classic status. Here it goes:
[bugs / fixes]
- treetops sometimes turn white (instead of green or purple) after a battle. Zooming in and out fixes this, but it gets really annoying...
- floating waterfalls at the end of rivers when they end on land (other people and myself have reported on this ad nauseam)
- return piers, logging camps etc. to their previous state where we can build them even if the city reaches the river/forest through snaking
[balance issues]
- nerf the dark sorcerer's armor and/or despair attack
- nerf the master scouts ability so it is not such a clear advantage for exploring and settling
- create "swarming" or "flanking" ability to give groups an edge over heroes and single units
- give governors an experience gain for staying in cities (linked to turns, city growth or buildings)
[UI/Tweaks]
- give us a go-there button for resources that are destroyed by the enemy (MUST HAVE)
- provide an "open/close borders" option in diplomacy independent from NA treaties
- give us a "teleport item" spell in order to move items from hero to hero
- alternatively, provide an "item vault" building in cities where we can store and pick up items
- allow outposts to train defenders just like cities
- provide an "auto-resolve battle without spells" and make the normal auto-resolve use spells
- give us an "auto-moving" indicator in the empire tree for units that are pathing (a yellow border?)
- give us the ability to attack heroes if we don't want to recruit them or leave them for the enemy - it is silly to recruit them just so we can disband them...
[content] (note: this last part can all come from mods so it's not as high priority for release)
- more items : we can never have enough!
- more summins spells
- more high-level monster bosses with high-level item rewards
- a great campaign - which I'm certain you are already creating 
This list is quite definitive, and (again imho) not hard to implement either before release or during the first expansion
If most of the above are addressed at some point before release, I personally will give this game a full 100% endorsement and keep it in my hard drive for decades to come !!!
