A few things to think about here.....
Firstly, not all clubs have approved disc brakes for use. So don't assume that you'll be able to race should you buy a disc roady. In any case for crits a disc framed bike is not needed and likely will just cost more and be a lot heavier than a standard road frame.
Geometry - Before buying something I'd realistically assess your flexibility and fitness level. Many pure racing frames (like the caad 10/12 above) are very aggressive and if you're not doing bikram yoga 3 times a week will likely be pretty uncomfortable and in the end will decrease enjoyment. The vast majority of road riders want to ride a pro level bike and in reality they should check their ego and ride something a little more upright and forgiving. This is especially true of mountain bikers used to sitting 'in' their bikes rather than on it.
Some bikes to look out for
Endurance/sportive geometry - Giant defy, specialized roubaix, cannondale synapse, trek domane,
Agressive race frames - giant tcr and propel, specialized allez and tarmac, cannondale caad and supersix evo, trek emonda (somehwere in between) and trek madone
If i were you i'd be buying a used bike until you get a feel for what sort of bike you should be dropping big coin on. Plenty of talk of road bikes all moving over to discs soon enough so seems a risky time to be dropping $10k before standards are settled etc. Having said that I just bought a brand new emonda ALR which was half price and for $1300 I cannot fault it. Phenomenal bike for the cash and would be a superb crit bike.
