I'm extrapolating from previous costs to predict 2015 (so this might be off a little), but gives you an idea:

Note, this is only my close estimation - we will know more tomorrow for sure.. but if you're like me, you want to know 'about how much'...
(The figures are based on base price * a multiple as you go up per stateroom.. for comparison sakes, a cat 3 is usually ~ 2 times inside state room price, a cat 5-6 is 1.55-1.61)
I think it's going to be pretty close to right.. for example:
2A2K = Cat 5, 11 night prices to about $3955+3955+1414+1448 = $10772 for 11 night.. we payed a little over >12 for the 12-night Med in 2013..
