Well... thats quite an interesting collection of posters there....
but to stay on topic, it has me wondering how they'll be able to differentiate the characters sufficiently (both in personality and magical power effects). Nanoha's outfit is pretty spiffy.... but I think most of us were hoping Fate would stick with the gymnast look.... perhaps her field uniform still does that... or maybe she pulls one out when things get tough later in the series and she tells the TSAB they're reacting too slowly.
I keep seeing all these shorts and cutoffs and thinking of the Hitchhiker's Guide line: "Sitting in his resplendent battle shorts...."
