Кусочки слухов продолжают появляться.Взято с варсира, степень достоверности не подтверждена.
Certain units to get Rage USR is one I've heard repeatedly. (foolishly didn't see the first post... oops!)
Sword Brethren areto get a special rule where when they are assaulted the enemy unit has to re-roll all* successful hits, at the expense of 1 attack. It's called "parry".
Land Raiders, when suffering a 5 or 6 on the damage chart* (so "wrecked" or "destroyed") gets one more turn where it rampage, think along the lines of the machine spirit going bezerk.
No horses as far as I am aware, bikes would be the direction (if any at all) for riding knights.
There is a named Emperor's Champion, he's meant to be the longest living EC in the Black Templars history, or somesuch.
*I'll seek clarification as it doesn't quite seem right in my head........
