Is it anticipated that DL will modify award chart as well? In our houesehold we have several SkyMiles accounts with significant balance. We (family of 3) fly to Europe once per year and this year we decided to fly in coach (to save miles for future trips). But reading about upcoming changes, I don't want those miles to worth nothing and thinking about redeeming for Business class. Would it be a stupid move? Maybe DL just wants to scary people to burn their SM balance.
