Sony Handycam
Old model not ready to exchange within in warranty

I had 285E Handycam model which was purchased 2 year back. I wanted to upgrade to CD model but they are denying in the sony showroom. One should be allowed to upgrade to latest by the same company so that customer will have latest. I am ready to pay the difference. But what i will do having two if not done?

Please help resolving smb!
