I do feel that reading is available, but it would imply the move action is performed stealthily... and nothing else. No hidden condition extending after the move action.
That would be fine if you 'attacked stealthily' by making a check with your attacks, but WotC_Mearls clarified that was not the intention in language that I believe admits no other meaning. Therefore you somehow need to conjure a hidden condition to cover the attack.
Surely, one should be able to have it one way or another. An identifiable issue at this point is that we're straddling both.
Which looks preferable to you?

You make the move stealthily, make your Stealth check as part of it, and if you succeed you end the move hidden. If you also started the move hidden and didn't break cover/concealment en route, you never actually stopped being hidden.
Why would the Hidden condition not extend after the move action? Until you or your opponents do something to end it, it should essentially continue indefinitely.
