some answers two,the revenge
@ogre3:ther're four knithg orders,if i remeber(i've to improve my mnemonic abilities)
yes,ther's the Achlector as Lord type hero
yes:your list of heroes it's correct
No,the stank will not be crushed by a single St7 hit like chariots
in HtH multibarreled pistols work like hand weapon and are "move and fire",multiple shot x2
Pidgeons are an equipment for eng.,low stregth fire weapon (sort of)
The zoo actually doesn't give the army anything rules wise (except for the karl's dragon)
Your wondering about core,special and rare units it's good...but remeber this

utriders are just an upgrade of pistoliers (which are a special unit,you've missed them in your list)
@kedlav:free comp. are not changed in cost (but could have great weapons)
@Dragonsbane:no teutogen guard it's NOT in the list
the WW knights have wolf hammer which grants a +1St bonus in every round of combat,they don't cost less
Flagellants if you take a priest become core unit and so i think they will be useful
Greatsword are not 0-1,but theri cost seems to me unchanged
@Ultimate Nagash:yes,morr's knights will be there
