We're still about six weeks away from "summer's biggest" party but it appears WWE has already decided on what music to play.

According to the latest Figure Four Weekly newsletter (subscription required), the top four matches for SummerSlam 2012 have been decided but are being kept under lock and key.

One of those matches will be, of course, Triple H taking on Brock Lesnar. While the former Ultimate Fighting Championship (UFC) Heavyweight Champion has yet to formally accept "The Game's" challenge for a match at the pay-per-view (PPV), my powers of deduction lead me to believe he will eventually capitulate to Triple H's demands.

I mean, the dude's face isn't just on the poster, it IS the poster.

But that leaves three other matches.

It's been heavily rumored John Cena will be facing WWE Champion CM Punk at the event, in a rematch from last year's headliner. Cena will be vying for a title shot during this month's Money in the Bank show and a win there could see him cashing in against "The Straight Edge Superstar" in August.

Whoever holds the World Heavyweight Championship will also be involved in a match, whether it be Sheamus or Alberto Del Rio. Perhaps a rematch should the Mexican wrestler manage to wrest the title away from "The Great White"?

As for the fourth, I'm at a loss at to what match could be put together which would rival the previous three.

The report also goes on to say a total of seven matches will make up the SummerSlam card with one being some kind of gimmick match.

Any predictions, Cagesiders?
