Rob,
I think WRC 2 is released on NA in this autumn - I read that from somewhere.
-------------------------------------------------------------------------------------------------------------------
Back to WRC3:
Now I have played and won novice level championship and 5 rallies left when I do that in professional level - as Tommi Mäkinen, Subaru Impreza WRC3 E-Spec.
(Expert level is still unlocked and I think for even begin that level you will need AFTER unlocking complete driving licence test...not sure though)
E-Spec? A-B-C-D-E. 5th evolution of this rallycar in season!!! Further you drive, your engineers developes new 'perks' for car: better ignition, fuel controller, sturdier parts, more torque, better aerodynamic. After 100 km completed driving you will get advanced version of current WRC car.
That sure makes more play for the game because there's 7 official WRC3 cars and if you want all 5 levels you need to drive 500 km with each car...
I also unlocked Suparu Impreza Extreme 03 car... Oh boy!...B-group is back..Kind of!
I tested the car on testrack and topspeed was about 320

And about wheels for ps2:
According to manual of the game Speedster 2, Speedster 3, Logitech Driving Force, GT Force Steering Wheel are supported. With pad you are able to use analog controls.
More whining: Mechanics?
On Pro level I haven't seen options for damage fixing. It looks like they do automatically fix the car as new even it looks like overhand knot after ss. You can only adjust brake bias, gearing and suspension. Poring...
Where is night?
I liked challenging nighttime special stages in WRC1 and WRC2, but I haven't sawn any in WRC3 yet! Unbelievable! One ss at Monte Carlo is on dusk, but no really need to have lights. I'm pretty disappointed if more demanding difficulty levels won't have night SSes.
RIP replay.
Like I did mention earlier replay mode is ripped too. You can't save your funniest/craziest/perfect stunts into memorycard anymore. You can't lock the replay camera, but you can change it...till game itself does change it to another by it's own will. I don't mind much about this but it would have fun to show your buddies some weird you managed to do in game...
Scenery:
Scenery is optimized to show further distance and more objects. Because limitations of PS2 technology, they have had to downgrade quality of objects too. No!...everything from your own rally car to surface you drive is better than in predecessors, but ground, trees and secondary objectives are simplified which you clearly see from replay. It doesn't effect on gameplay so that's ok.
Goodies: Earlier mentioned test track - maybe even more bonustracks when you do advance in game.
Driving:
Feeling on various road surfaces are great. Gravel is really fun to drive, snow as well, tarmac too - althought all rallygames still makes driving on tarmac feel bit weird - but direction on this game is right.
I don't know how good or bad handbrakes are in REAL WRC rallycars, but in this game that's pretty useless. Normal braking will make you faster and even better looking. Heh. Forget the handbrake.
Cars feels more heavier and more real. You can bush and throw them like in other games, but they act more real and light touch won't kill the speed or spin your car.
That's goor bridge to tell about damage model:
Light damage won't effect much on speed or controlling the shitwreck but damagemodel is very good improved from predecessors. Do-it-yourself-cilin-colin-car is possible (althought due licencing issues there's no Colin McRae in game - but his bro is!). strong smashes cracks or drops your windshield/other windows, makes bodywork look like raisin, hood/bumbers/spoilers can tearn off.
I haven't tried to do damage for PURPOSE, so I don't know is it possible to kill engine or dumb one, two or three or even all wheels off.
Special Stages:
Total 9 in 14 rallyevents. Difficulty level decides how many ss you have on event: Novice 3, Professional 2+2+2= 6, Expert 3+3+30 9. You can save game and fix car after each 'day'.
New in WRC game serie is crossroads, if you don't pay attention on co-driver you just might pass it till timer sends you after 3 seconds on right way. Heh. Very funny to drive those...even middle of cities.
Music:
I don't like music on driving games so I have turned them off - but it's somekind of wrc related dancemusic.
Overall:
Good rally game. Evolution of WRC 2 but looks like they have make few compromisses.
Better than CMR3.
