biggest points for me:
counter attack is no longer even a rule for us: we have to do a LD check to do what we've been doiing all along?
no matter the odds is gone: why? it's not that over powering gosh!
true grit: says use as written. clarification questions below *
Fenrisian wolves can't turbo boost but nothing stops them from being ablative wounds now !!
no more two venerable dreadnaughts: sad, but expected 
wolfguard battle leader may take an assault cannon: my question is what happens when you have 4 base attacks, but you're not carrying a weapon? I know I'm going to start taking assault cannon and storm sheild terminator battle leaders 
wolf guard battle leaders can come in deployed with other units...but it doesnt mention other leaders? does that mean my rune priest can't drop pod in with my grey hunters?
Things that are missing(from my memory):
no more rulings on storm caller means we get to strike first.
no ruling on wolf pelt means it stacks
* for new marines who are equipped with a bolt pistol, bolter and CCW. do they get 3 attacks on the charge? 1BP+1A+1Charge? and do they get 2 attacks when charged? 1BP+1A?
if so then true grit no longer makes grey hunters better CC fighters. thanks for any help on this
1) The LD check is just to see if the squad benefit from the +1A for CA. You still get the 6 inch mug in move in CC. At least we can have te extra attack....
2) NMTO is gone. Just to get rid of one less
USR. Ill put money that they will put stubborn in our next codex so its to sand that out, but watch this space.
3) Fenrisian wolves, it pains me to say, were
always ablative wounds, and Im fairly sure they never could turbo boost, but Ill await confirmation by DB or someoen.
4) As you said, expected.

2 Ven dreads, wandering around? Not exactly the most healthy thing for an enemy to do in any circumstance.

5) Your priest can drop in with your
GH's as far as I know, its just that the WGBL is a bit unclear as to his position in the army.
6) WGBL with an assault cannon has got a weapon, the Assault cannon.

He will hit hsi enemies over the head with it

It will just count as a
CCW with no special effects.
SC is your call, it really is. Everyone seems to be at 6's and 7s over it. Use it as you have always done.
Wolf Pelts, well, Im stacking with mine, so.......

It does.
GH with Bolter and
CCW get 3 attacks on the Counter Charge (one profile, one 2CCW, one CA), and 2 when they charge. But then again, thats what you want your
GH's to do; to get close enough, hold a position, Rapid fire at the enemey and shatter their charge when they do.
Happy trails
