UK Impreza models due in next few months

I'm hankering after a Impreza but quite like the understated look rather than in your face.

I was thinking of a standard WRX with a Prodrive enginer upgrade rather than something like an STi. But I really want full performance.

The figures on this new STi which is in Autocar this month is amazing. is it

Do the Prodrive WRX upgrades still keep the warranty intact?

Also whats the plan for Prodrive P2, is that would soon????

Cheers
