the hot focus is AWD throck(atleast some of them are and they claimed to be bringing an AWD one over)
HP wise its a small displacement turbo so it should be easy to coax some more out of unless its netuered with a dinky maxd out turbo ala the og WRX in the US.
the WRX starts at ~26K, has less HP(265 v 305)
26K for the V6 premium(lets be honest, the RS will be kitted out inside so a base stang wont compare that well) or 30K for a GT. The stang is bigger, rwd and similar power unless you add the V8
if they priced it in the mid 20's there is a market, but the closer to 30 they get it starts to infringe mustang gt territory
without AWD its a waste of time of course.
All of the Foci are FWD, aside from some one-offs. The Euro Focus RS is madly expensive, and at ~300hp, only a moderate match to the V6 Mustang, which outperforms it 0-60, 1/4 mile, top speed, skidpad, and slalom (mag benchmarks, posted in another thread a test of the 2010 RS).
The 225hp ST will be around $25-$26k for not even fully loaded ones (probably without Nav at that price), that leaves the RS model with much more expensive differential, brakes, larger turbo, various body panel differences, etc, probably costing at minimum $31k+. In the UK (apples to oranges, but still), the thing is north of £30,000, and the upcoming Focus RS Clubsport is £35,000+. Neither are AWD, just FWD with a trick differential, a la the old Prelude SH (spins inside and outside front wheels at different speeds to reduce understeer). In the end it's just not very impressive or sorted out. Watch the TG:UK from a couple of weeks back, the hugely expensive RS500 (not the run-of-the-mill RS mind you) loses to an STI, and looks a mess going around the track, popping onto three wheels at many times. Clearly at the very limit and perhaps a shade over FF drivability.
EDIT : For a sense of how $$$ those things are over there, 30k british pounds is $48360 at the moment. The UK Ford Fiesta for contrast starts at 9995 british pounds, or ~$16,000.
