OK so we have several threads on why Susan Boyle (SuBo? WTF?) shoudl NOT win, but this one tries to determine which act will win given the possibilities.

Don't forget also that nothing has been left to chance by Cowell and Co (is it ever?) - note that all the SF's had essentially 3 goodish acts and 5 rubbish efforts, so we get a basically reasonable final.

OK we have to assume (also reasonably) that tonight's semi-final winner will be Greg Pritchard (the Counter-Tenor).

I'm also reasonably certain that the final will be won by one of the 5 semi-final winners, viz.

Susan Boyle
Flawless
Stavros Flatley
Julian Smith
Greg Pritchard

From these, I think Diversity will affect Flawless' vote as will Shaun Smith affect La Boyle. Given the Hairy One's antics this week this should see her lose a few votes also.

In terms of pure variety, Stavros should be the winner, but in terms of talent I see Julian Smith winning, but ONLY if he doesn't repeat himself with his audition piece - I trust he has more of a repetoire than that. Greg Prtichard could win on off-the-wall wackiness alone.

Tough call. Bring it on!
