I don't *want* to adopt a new format. It took me years to even adopt DVD, and I could see clear benefits to adopting it as a format. Now there's a new format (two, rather) on the horizon for which I see no clear benefits; only deficits in my bank account. I will adopt a high definition high-capacity format when I am forced to, because I don't see myself wanting to make the transition.
If my thinking is representative of the general public, then anyone's taking a financial risk on a new format at this stage.
