Sure, we know there is now probably less than a 50% chance that the merger will happen, but we are still allowed to speculate: (cue harp music)
The "Platinum Plus" level (75k) will contain a few of the bennies of EXP (maybe like 2 SWUs and/or waived award change fees), and will be attainable for life at 3MM (although EXP for life will still not be attainable). And of course P+ people will outrank regular Platinums on standby and upgrade lists, etc.
OK, back to reality. Ain't gonna happen, right?
