Next year might be a watershed year in large sensor camera choices. But its more important that you get your feature done in a time frame appropriate to you, so I hear you. You have to use the best choice available now. We're not getting any younger and some of us are getting older, FAST.
My circumstances may be a lot different to everyone else, I want to start shooting my feature early next year and it is going to be projected probably on 35mm and 2K so I don't want to be doing any nasty 24p conversions and have a lot of jello on the big screen. plus I'm self financing the film and hire prices are insane here you can buy stuff for what it costs to rent for 10 days.
