Well it appears that a number of people have begun to play test 8th Edition Warhammer Fantasy. Found some reasonable summaries among the most informative was this one from
http://ineptusgameus.blogspot.com/Movement
# The phases are all in the same order, so magic is not the first phase!
# I didn't get to see this phase too well as everything was set up to fight but it seems that movement is similar to War of the Ring/Fast Cav so units can slide or shuffle around on the board
Shooting
# Everything with a missile weapon can shoot in two ranks.
# If you have a bow you can volley fire which the unit can shoot with more ranks (I'm not too sure if it's one or more)
# If the unit is on a hill the only shooting benefit is for LOS
# Speaking of LOS, everything is true line of sight!
Charging and Close Combat
# LOS arcs are the same for everything now - everything has a 90 degree LOS
# Charging is indeed now base move plus 2D6 (or 3D6 if you are move 7 or more)
# You make your charge reaction before the charging unit moves and you can measure the distance between the two units
# Failed Fear tests make a unit WS1
#ASF + Higher Initiative grants re-rolls!
# Close combat is done in Initiative Order now
# The second rank can attack now in close combat but only gets one attack. Cavalry units benefit from this but only the riders in the second rank can attack
# Spears attack in an additional rank as well as the second rank. So spear armed units can attack with three ranks!
# Rank Bonus - Still 5 models to get a rank bonus but Ogre sized units get it from 3 or more models
# Horde Rule - Basicly double the number of models needed to claim a rank bonus and you get an additional rank to fight with (so 10 wide for infantry or 6 wide for ogre sized models)
# Stomp! - Ogre sized models get an additional attack after their attacks while larger models get d6 additional attack!
# You can wound anything with a to wound roll of 6! So S1 can wound a T10 model!
# War Machines and Monster and Handlers are different in combat now. When fighting you hit the WM or Monster as the crew hide behind them in CC (so you wound the WM or Monster). This info is a bit vague as I can't remember the details as we got disturbed when he was explaining and then moved on to the next thing.
# Outnumber is gone!
# If you loose a combat but have more ranks then the enemy you are stubborn
# Fleeing is a bit different now. If you are Move 7 or more you roll 3d6 but discard the lowest dice
# If you flee through a enemy unit you take d6 hits instead
# If you wipe a unit out then you may take a leadership test to redirect into another unit near the flee path
War machines
# Guessing is gone. Place where you want the shot to go and scatter as normal
# Templates are now like the Skaven ones - ie no more partials!
Magic
# Generating Power Dice is indeed 2D6 and the opponent gets the highest dice as his dispel dice
# All wizards can channel more power dice or dispel dice on a roll of 6
# You are capped at 12 power dice
# All the core spell decks have seven spells
# Picking spells is as per 7th but you may always default to the 'zero' if you don't like what you picked, plus no wizard may know the same spell as another wizard in your army. So no more two lvl1 fire mages knowing fireball each!
# You can roll up to 6 dice to cast a spell for any level
# You add your magic level to your casting or dispell roll
# A natural 1 or 2 is a failed cast (which limits single casting)
# You miscast on a double six now but the spell goes off and the wizard takes damage as he struggles with the backlash of magic
# Miscasts range from bad to really bad - So a double one is a big 5" template centred on the wizard and everything takes a S10 hit!
