If they do get combined, then it's huge perk for CO FF as UA 1P is definitely much more valuable than CO silver.

Well, while I don't even know what "1P" means or why it's more valuable than CO Silver, I think that's getting ahead of things.
First they have to decide if they're combining MM balances.
Then they can decide what the benefit of 1MM, 2MM etc. is. And they can even decide whether or not to grandfather existing MMers in to the prior program or not. "Lifetime" UA status may have ended with the birth of United Continental Holdings or whatnot...
