I've gone the opposite way - I've been replacing my American pronunciations with the British ones, like leverage starts with lee, like in lever, and that (software) patent starts with pat not pait.
I think it's in response to my younger friends and colleagues sounding, to my ears, increasing American - they say gotten, zee, and on accident (things that are often more consistent, but just not cricket British). I'm old enough to remember the sound of dial up, so I probably wasn't as exposed to US media growing up.
