Will Nook be sold in UK Supermarkets soon?

I have just read and inwardly digested the news that Sainsbury's is entering the ebook market

So how long before they (or one of their UK rivals) do a deal with Barnes and Noble.

The Nook will arrive in Britain soon and it would make sense to be sold in supermarkets as well as bookstores. Waterstones has a deal with Amazon and WHSmith's with Kobo but I can see that in a year or two that Tablets and ereaders from a whole range of suppliers will be available in Supermarkets.

So will it happen? I don't know but it would make sense.
