The pushing speed increase is the thing I'm looking forward to most. There's a good five or six maps where I run to the PaK or 6-pounder as soon as I spawn and it takes forever to get where I want to. I don't mind this, but I would hardly complain if it took slightly less than forever.
For example, the PaK 40 spawning at Ghazal on Supercharge - I love to grab it and take it up to defend Sidi, and usually it works nicely since I get in it, get it pointed in the right direction, put it on teamchat cruise control and have a smoke whilst driving it into place. Didn't work so well earlier today, since the Spitfire killed me the first time, the Beaufighter the second time, and the British had capped the first four flags by the time I got it where I wanted to. Much the same with the 6-pounder at La Prieure on Goodwood. I've got no problem at all lying in wait for 10 minutes for my first sign of enemy tanks, but the only thing in FH2 that ever makes me genuinely angry is one of those rounds that happen every so often where you are forever just swearing at yourself and thinking 'If I just had ten seconds to prepare and get my bearings I'd have ten less deaths this round'. I'm looking forward to the changes very much!
