I'm hearing a rumor that Boyd Gaming's "B-Connected" players reward program is being modified to add a 5th level; Pearl.

The current levels are: (low to high)

Ruby
Saphire
Emerald
Onyx

Word of mouth has it that a fifth level will be added around 23 August. That level is will be desoignated as Pearl, and it is a higher level than Onyx.

But then again, this is a rumor at this stage.
