These knobs are just quick and easy access knobs. You can always controll these parameter with going into the effects menu (press and hold the respective effects block button).
If the lunchbox is worth the wait depends on your preferences. Apart from the quick effects knobs the rack also doesn't have the LED rings around the (tone) control knobs which I would be missing. On the other hand the rack has a front USB port which is quite nice.
Decide for yourself which features you'd prefer.
Personally I just love the form factor of the lunchbox 
i got both versions and i much prefer working with the lunch box for editing etc,once you get used to the leds on the lunchbox you really miss not having them on the rack.
Don't get used to the LEDs on the lunch box to much, after a couple of months they'll start to die. 
...And so its gone..
oh no,thats sad,but mine are still fine after more than a year 
Can the LED's be replaced if they go out? Does it have to be sent back to the manufacturer?
Yeah, I have heard many complain about the LED lights going dead after a few months. This seems like a defect as LED lights should last a very very long time without failure. Living in the US makes this a major issue for anyone wanting to buy a new Kemper, even under warranty due to the overseas shipping and repair issues.
I dont think you have to send your kemper to germany. I think they have some qualified repair person in the states. Just ask kemper about that.
BTW, after using my KPA over a year, i have no problems with the LEDs.

They do have service centers in several countries so no need to ship it overseas in the US.
I think you can locate the service centers in this link. http://www.kemper-amps.com/pag…ers_and_Distributors.html
On topic, for my needs I prefer the lunchbox kemper design.
