i tend to keep up with console releases so whatever format it comes out on i'll get it, i use my PC for business so i doubt i'll get it on that...
lets just go with the numbers Oblivion sold more on Xbox360 than any other format, DLC sold more on Xbox360
i bet Todd Howard's inbox is full to the brim already, imagine if he confirmed development of TESV
Oblivion took 2-3 years, i would imagine we'll see it on all current formats winter 2010/2011, but nothing official until summer 2010, june 15th at a guess
my hopes are more about content, gameplay etc etc rather than what format it comes out on
dont get me started on the failure that the PS3 is, believe me i know
