Is was announced last May, so its unlikely to be replaced soon. Scanners do not sell very well, so there is no incentive to put out major new models. I've had my Epson photo scanner for 3 years, and it really hasn't been improved upon by much.
When they come out with a USB3 scanner, it might be worth taking a look at. Speed is the biggest thing if you are scanning hundreds of old negatives, and I have thousands left to do. For slides though, the low cost photo scanners don't do well enough for me.
