My WP7 phone contract comes to an end in October/November, but I bought the phone outright at the start (it was cheaper over the course of the whole contract) so I won't be offered any kind of automatic upgrade.  I am undecided if I will ditch my current phone and go for a new WP8 one, or just keep what I've got.  It will probably come down to whether I decide I want to write WP8 apps or not, rather than my usage as a 'normal' (non-developer) user.

you can sell the phone and use that as a lil down payment for WP8... my contract is up in Nov too
