Story lines: Chris Hoy (left, foreground), a 30-time world or Olympic medalist, leads a track cycling juggernaut; Somalian-born Mo Farah goes for a distance-running double; big Games for sailors, equestrians ... and Andy Murray?
Don't miss: Brothers Alistair and Jonathan Brownlee battling for triathlon supremacy; first all-Britain soccer team since '60.
Hot button: David Beckham and world No. 1 taekwondo athlete Aaron Cook were left off their respective teams.
Outlook: The last time London hosted, in 1948, Britain won only four golds; there will be lots more this time as the Brits outdo even their stellar showing in Beijing.
