Yes, all current devices will be upgradeable to the next version of WP. That is WP8.1. That is the only strong claim being made in any of those articles, which, BTW, can always be traced back to a statement made by Mr. Sullivan and has absolutely nothing to do with support cycles.
That all current devices will get WP8.1 is undisputed. Anyone getting anything more from any of those articles either can't read critically or doesn't understand the intent behind MS' support cycles.
And... as previously stated, nowhere is WP9 ever mentioned.
"Current Windows Phone 8 devices are expected to be fully upgradable to Windows Phone 9."
