Who would win? Taking in mind, you can't assume the players match the value they are on paper - i.e. form at the time has to be taken into consideration (e.g. Ponting looked terrible during the 2010/11 series).
A typical 2013 side:
A typical 2010/2011 side:
Think it would be pretty tight. Would give it to the 2013 side though. Every aspect of the bowling is superior - Harris >Johnson, 2013 Siddle>2010 Siddle, Starc>Hilf, Lyon>Doherty. Plus the batting isn't really much different when you take into account how woeful Ponting and Clarke were. The strength of Hussey is probably what slightly tips the batting towards the 2010 side.
I would say the Eng 2010 side was better in both batting and bowling than the present one though, so it's interesting we are probably gonna be going down 4-0 here, an even worse showing than before.
