Wow! Thanks for all the responses. I had no idea that Sony is going to the EPUB format.
I found this at the web link "Books that have been purchased from Sony’s eBook store in Broad Band eBook format (BBeB) will continue to work on existing devices. When the store is converted, customers will be able to re-download their previously purchased books in EPUB format. " Thanks igorski!
Now, I just need to decide if I want to get another reader!
