I was in a cell phone store yesterday (Three UK) and they are offering a free upgrade to W8 when you get a Win phone 8 from them. I asked why this was being done as he was pushing it quite hard in an attempt to get me to buy and the shop assistant told me off the record that WP8 wasn't exactly flying off the shelves and W8 hadn't been a huge hit either. This is obviously just gossip but makes you wonder.
