Given how Citi's employees apparently leaked the info. about Prestige applications being stopped, maybe Citi held off on sending out any info. about a "refreshed" Prestige to avoid similar leaks. Or maybe the "refreshed" terms haven't been fully determined yet.
As I recall, DoC updated his post from "will be discontinued" to "won't be discontinued" within an hour or two. There's simply no way Citi changed its mind in such a short timeframe based on some internet comments. People yapping on the internet wouldn't have changed the card's profitability one bit.
