Good question, James.
Given the choice, I would definitely prefer to see a BB2 type mix of contestants, mainly because they seemed to genuinely form strong bonds and friendships in the house, which have continued in the outside world. (Paul and Helen, Brian and Narinder, Bubble & Dean, etc.) Watching these friendships develop, and how they coped when one of them was evicted was fascinating viewing.
Although a couple of the BB1 housemates did form friendships of a sort, in the main they 'played the game' far more as individuals and tended to avoid forming close bonds with anyone.
As for BB3 - I'm sure the mix will change again. Possibly we might see a couple of older housemates this time, and I do think they'll avoid putting in people with too similar characters to, say, Brian and Helen.
We'll know for definite on the 24th!
