haa.. Guess the main reason why canon dslrs won't have a swivel LCD because it might not be possible. Well currently. *We must keep in mind that the only purpose a swivel LCD should serve is to be able to "see" at difficult angles* So with that in mind, to enable "live feed" to the LCD, canon would have to lock their mirrors to allow constant image feed to the sensor. From this point, when you click the shutter, there'd probably be a "lag time" from shutter button release to shutter open. If you don't understand what i am saying, you probably need to understand how dSLRs work.. But then again, it's just my theory
