It's not just the country but the whole world that is waiting for one question to be answered i.e Will Aamir Khan host Kaun Banega Crorepati 4?

Various thoughts must be creeping in his mind. The popular one among fans and media is will the actor be comfortable hosting a show whose predecessors is arch rival Shah Rukh Khan and Amitabh Bachchan. Despite his great showing, poor Shah Rukh couldn't escape comparisons with the original host Big B.

King Khan didn't help his cause by doing Don, whose plot was inspired by the original Bachchan starrer Don. If he takes up KBC, will Aamir be accused of aping Shah Rukh Khan?

The wise mind will say no. According to sources, comparison is the last thing on Aamir's mind.

"These things simply don't matter to Aamir. The only way he would come on television is by doing a show that caters to social cause. At the moment, he's got two projects in hand – both by BIG Synergy.

If KBC doesn't work out, then Aamir is likely to take up the other reality show, currently untitled. The common thing with both is that their principal aim is social cause. It's precisely this thing that has evinced Aamir's interest in coming to television, " said a source.

If it materializes, Kaun Banega Crorepati will have a new format. Last year, there were murmurs of incorporating the Slumdog Millionaire mania into the show.

Throwing light on it, the source says, "Yes, earlier there was such a format wherein you would invite one contestant from the slums to earn rupees I million in a day. However, that's been done away with now. New format, new rules will be in place, but one thing constant will be the social factor."

SET Max has already bagged the exclusive rights to telecast Aamir's 2009 blockbuster 3 Idiots. Is this a sign of things to come?

"It might be, but so far, there's nothing on paper. However, we're getting positive feelers from the superstar. All that is needed is his approval, " concludes the source.

Until then, we'll keep our fingers crossed.
