I think the green one looks the absolute bollocks, fooking love it!! It will always be a shame Ford didn't go the 4x4 400BHP 'Evo competing' route BUT from owning a fairly potent example of the Mk1 FRS it doesn't really bother me that its FWD. Ok, so its never going to be able to be tuned to have the straight line pace of a 500BHP+ Escos/Evo though.
As for the brakes, I agree with Mike. It mentions all the other key components but doesn't mention anything about the calipers. I also agree that this is a let down.
Not to say the setup they have in mind won't be good but imo it should at least come with Brembo 4 pots.
Also, regarding track work and RS owners,
my Focus was used on track/the Ring within the first 6 months of ownership and over the last 2yrs it has ONLY come out to do a trackday or to drive to and from a trackday! lol Quite a few of the FRS boys 'play' at trackdays too doing parade laps etc. 
IMO it should be produced with this in mind given the growing popularity of track days, it has the diff, the seats, the power (sort of) and theres talk of it being available with the option for different tyres suited to track days, so it needs to have the brakes.
Time will tell, either way I'm now really excited about seeing it on the 23rd.
