NOBODY!
Do I have to buy it now and where
he has been in the wwe since 2000 till now
Yes. CM Punk is the current reigning WWE champion. This is his second reign as the WWE champion and he has been a champion for over 100 days now. He won the title in November of 2011 when he defeated Alberto Del Rio. He has succesfully held the title even after the Elimination Chamber match where he faced 5 other WWE superstars. He will face Jericho at Wrestlemania 2012 for the WWE title
Right now - No idea. As of now CM Punk is the WWE champ. He retained his title in the Elimination Chamber Pay per view. He is scheduled to face Chris Jericho for the WWE Title at Wrestlemania. Cena has a match with the Rock at Wrestlemania. So, if at all Cena wins the title again, it will be after Wrestlemania
As of December 13th 2009 John Cena was still the WWE Champion. On December 14th he lost the title to Sheamus at the TLC PPV in a Tables Match.
It is Judgment Day. Some matches that are set as of now are Randy Orton vs. Batista for WWE title and Edge vs. Jeff Hardy for World Heavyweight title
The two titles are not combined. Currently the WCW title is renamed world heavyweight title and is currently held by Edge and the WWF title is renamed as WWE title and is currently held by Randy Orton now undertaker has the heavyweight championship wheras john cena has the wwe championship
No.The Rock is now retired but is a movie star.
CM Punk is the current reigning WWE champion. This is his second reign as the WWE champion and he has been a champion for nearly 4 months now. He won the title in November of 2011 when he defeated Alberto Del Rio. He has held the title ever since
till now,sheamus and punk are guaranteed,and the remaining three are still unknown
As of now - Never. Jeff Hardy is currently wrestling for TNA - Total Non Stop Action wrestling promotion. So, he cannot be the WWE champion. If, in future Jeff signs up with WWE and manages to impress people there, he may end up with another WWE Title run. But, as of now, his return to the WWE is just speculation. He is already a one-time WWE champ and has also won the WWE tag team titles and intercontinental title many tmes.
He is gone for now but there is no way that he would have been allowed to just walk out with the title if wwe had not agreed some kind of deal for his return however after raw tonight we probably wont see punk till royal rumble
