Jeff had mentioned in the quick look of Gen Knoxx that the enemies scaled. This is not true. Their levels are hard coded like they are in the main game.  Thats not to say enemy levels in borderlands don't ever change, as they do get higher in playthrough 2...but its simply just hardcoded a higher level...not an actual scale.  
 
Also be aware that the main game and zombie island won't scale up after beating Knoxx. So, if you are lvl 61 and return to those they will be a super cake walk.

well, they do rescale to the 58-61 range, but they dont dynamically rescale. You just flip the "rescale all the enemies in the dlc" when you beat knoxx the first time in pt2

Wait, so what would you call the jump/drop in enemy levels when another player joins/leaves the game?

I just beat the main game and started playing Knoxx on playthrough 1, is this not recommended?

Basically this means that after you level up to 61 in the DLC, you are limited to playing in the DLC/Moxi areas if you want any challange and/or loot. As the main game and Island will remain with lvl 50-51enemies and lvl 48 loot max.

So, let me get this straight:  A player can beat PT 2 of General Knoxx and nothing scales all the way up to 61+? That is some bull. What should be done (and a lot of people on these forums as well as on Gearbox's forums agree) is that when you finish playthrough 2 of General Knoxx, that everything in the world scales upwards to meet your new max level, therefore creating replayability to the entire game, once again!

My question, is does being lvl 61 make Mad Moxxi beatable?

the cool thing about moxxi arenas scaling up to 61 is it kinda breaks them and makes them super easy.
 
like i'm not getting badasses in badass waves, just normal guys. and the lance you fight aren't the upgraded knoxx lance, they're just the plain old weak to corrosive lance.
 
also there's still infighting, so pretty much all of the mixed groups will fight each other.
