I just did myself, as I do not wish to place my spend (or pay the annual fee) on a DL Amex Card that will be earning SkyMiles if those SkyMiles are to be devalued as the rumors here suggest. If that's the case, I'd rather put my spend on a Chase card.

Of course, I doubt American Express will offer any insight, but perhaps if they realize that their loyal customers plan to cancel their cards and switch to Chase if these alleged rumors come to fruition, American Express will exert some influence on DL to scale back.
