There is no hope for HMV. Their profit forecasts for the next few years are a desperate attempt to protect the share price, just as their 'diversification' into stunts like in-store live entertainment was a desperate attempt to keep footfall levels high. Tower Records did what they do far better than them - as did Virgin. And they went ages ago. Zavvi was always a hopelessly lost cause.
HMV are in for a perfect storm. The megastore model for selling DVDs and CDs is an iTunes-inspired bust. And their Waterstones outlets will go the same way - again courtesy of iTunes, with a lot of help from Amazon.
The good news is we may see the return of smaller specialist shops - both for books and music. (This is already starting to happen around where I live.) Frankly, I won't be unhappy to see HMV and Waterstones go the way of the dinosaurs.
And dune, PLEASE put whatever you have left over from Desire into HMV. For me.
