Ugh, hope that will be customizable... I messed around with such effects a lot on Beryl/Compiz back in the day, and I can say that they become annoying after a while. Having non-bouncy slides on something like a quadratic curve seems to work the best. Too much animation just start becoming visual noise, often making you feel like the UI is slower than it really is; even if the content already loaded, is on your screen and is usable, if there's a menu/tab animation still running at the time I often found myself waiting for that to finish as if it matters.
I specifically turned off all my animations in Android because it's distracting.
