Howdy sootyboy, and welcome to CPF,
Well, none of us has the new Mag Cree drop-in yet, so kind of hard to say. You could e-mail the guys at batteryjunction.com and ask them, as I think they have a prototype.
My feeling is that you are probably going to be fine with the K2, and could instead use that extra cash for a another complete light, like the upcoming release of the Rexlight 2.0 which is a neat little Cree AA light coming out soon. Those folks who sign up early will receive an e-mail when it is released giving them an opportunity to buy it for only $30 shipped. See this thread for details:

I'm not trying to sell you a Rexlight, just pointing out other possible uses for that $30. Of course, if you want the best and brightest for your Mag, then yes, the new Cree drop-in will be brighter.
However, LOTS of new lights will be coming out in the next few months, so an even smarter option would be to hang around the forum and read, read, read. Learn as much as you can about what's available now, and what is coming down the road in the near future. For instance...... you should definitely go here:

and here:
http://flashlightnews.org/
Those are 2 good resources for learning about flashlights. Ok, sorry to be so long winded, but it's easy to spend money here, and I just want to make sure you get started right!
