I have yet to get in a game, but Darien over at Battle Bunnies is 3 games in and has a real good overview of what he thinks of the new edition. He goes into the details, and talks about shooting and close combat, the two phases I am concerned with in 8th edition.
Shooting continues to appear very powerful in the new edition.

and one thing to note.....is that charging needs you to be within 1" to fight, not at 1". This can make a big difference.
