i'm thinking of selling my 5d and upgrading to mk ii. it seems that a mkii costs about $2250 brand new. when mkiii's come out, they will probably cost like $3600, right? will the release of the mkiii have a big effect on the price of mkii's new or used? i imagine the influx of mkii's for sale from people upgrading might bring the price down a bit, but nothing worth waiting that long for, eh?
