My understanding is that patch 3.0 reduces the XP requirement, per level, from 60-70 by around 30% (slightly less I think). You can log in to the PTR and see how much the XP needed moved down, someone did that recently and I saw it was around 30% per level.

You can already do 60-70 via quests and skip all the collection quests, although you will only have around 1.5k or so gold at the end (if you save all 65+ quests till 70 you can knock them out and end up with almost 5k). So hopefully it'll allow more gold questing at 70 with the XP curve changes.
From what I've seen on the PTR the amount needed to level has been lowered 200k xp each level. So the lower 60s are affected alot more while 69-70 isn't much of a percentage change.

I've read that kills give 20% more xp. Not sure about quests though.
