Fantastic news of a MAJOR update with 1Z. I will be curious until it arrives but would note a few things I hope to see before considering what ballet to cast. 
A) The game pace has to slow down. The current pace is very fast, as in, I can buld a City to completion, with alot of Tech buildings in place, in no time. (4 turns for a Hut, that all then morph into Houses...)
The exponential cost of every city has to be corrected. If this was a anti-spam objective, fine, but with the current Shard and Resource distribution model in place, and seeing some of the requirement #'s included on certain items, it is imperative that we can build and maintain 3-4 ciites in order to properly determine how the Army building mechanic will look in the near future. (and no, I do not consider that point a balance concern)
c) As stated earlier, the Quest system has to be tweaked to include the Vista 64bit (the \Program Files(x86) structure is in place but empty) install scheme. I also use the "workaround" but can't help but feel as if I may be missing something based on Forum chatter in that regard.
d) Can the Trolls be toned down a tad. They are killing off the competition before we can get up to speed. They also pretty much need to be avoided early or your SOV gets a free ride back home. 
P.S. I am pysched..
