We now know who the houseguests are .. but what do we really know?

CBS introduces the BB10 houseguests ...

My initial impression of the Big Brother 10 cast is one of elation because I sense a tremendous summer forthcoming. None of these people know each other. We have a wide, wide variety of age groups represented, including a 75-year-old and a 53-year-old, which rocks.

We've got die-hard conservatives and liberals.

We've got a gay bull rider and a woman suffering from extreme OCD.

Big Brother producer Allison Grodner says that BB10 is a back-to-basics season, and I think many of us dissatisfied with BB9 welcome this. Grodner did say that there is a twist of sorts playing out before the houseguests even enter the house.

Wonder what THAT could be?

The story before the story, before the show gets under way if you will, is Gerry MacDonald. Some stories have his name spelled with a 'J,' but the Associated Press has it with a 'G,' so I'm guessing it's Gerry. But this 75-year-old guy is a huge fan of the show and has watched every season.

He has gotten into very good physical shape so that he can care for his wife, who was recently diagnosed with Parkinson's. He's a Korean War vet.

During this morning's introductions on The Early Show, he said, "CBS will get their money's worth."

Do you find yourself already rooting for this guy? I do.

Alas, it really is too early.
