It's because no-one can predict how a series will turn out, it's doubly important the producers not only get the right mix of house-mates, but safeguard the best house-mates from being evicted too early. That's why last series was so dire as the mix was completely wrong with too many dull people playing a game and badly thought out rules that had the most interesting contestants leaving first (Anouska should never have been allowed to have left so early).

I can't predict how BB 5 will turn out, but from what I've read from links via this forum, I am optimistic about the type of contestants the producers have lined up, so it does seem, finally, they've listened to the concerns people like me have been moaning about on boards like this.
