Went ahead and called to upgrade to the WOH Card. No issues other than the rep telling me that the 2000 bonus is targeted and he couldn't guarantee that I'd get it. Product change was quick and easy; new card logo already showing up in my Chase account.

It's always a little unsettling when the blogosphere jumps and down to hype a card. Note that price and return protection are eliminated from the card. There's a landing page with more info now: https://www.chase.com/personal/credi..._hpmasthead_en
