Looks like Marriott has released some information regarding the Reward Program integration between Marriott Rewards and Starwood Preferred Guest.
There isn't a whole lot in there we didn't already know or assume, but there are some admissions regarding the two programs and their strengths & weaknesses. But, like Ben states at the end, I will always be skeptical until the end... and even a bit after. He references the US airline mergers, which is fair in my opinion. Let's just hope Marriott doesn't go full Delta on us and try to effectively kill the program. Not to say UA and AA haven't gutted their programs either!
