I am doing pretty well.

Johnson's only 2 wickets from the top and Clarke's the top scorer by some margin.

Why not wait another 15 days and do it after the series is over?
 
I think Australia would retain the Ashes.

England had a great chance in the third test, but weather played spoilsport.

Aussies have psycological edge as of now.

England electing to bat again and all out for 220 in three session that should be the end..

Everything points to the Aussies winning, but you can never underestimate an England team on home soil in such a high profile match.
