Actually the way understand it is that as DM will not exist until spring, that if one qualifies as PM this year (2009), one is getting 6 PMU's irrespective of whether one gets DM or not, everything beeing announced is for the 2010 programme, we have all been flying and earning in the 2009 programme, and according to the rules and regs ond benefits, qualifying for PM in 2009 gets you 6 PMU's in early 2010. From when one arns in 2010, if one is Platinum, one will earn 4 SWU's and receive them in 2011 (or in 2010 if one achieves PM for the first time in 2010).
Irrespective of whether a DM gets 4, 6, 10, or 1000 SWU's, does it say anywhere that we are getting anything less in early 2010 based on our 2009 flying. In fact Delta has been very adamant over the last six months that nothing was changing regarding this years flying/earning, etc.
