Siri headed to iPad with iOS 6 ?

I think Siri would be nice addition to iPad.I heard that 4S has earsmart technology which makes Siri to work effectively in relatively noisy areas.

So if siri is coming , expect it to come on iPad 2 and new iPad (iPad 1 left out) but still i think its not fair because in youtube 'ported' siri via jailbreaks on iPhone 4 , iPod Touch worked perfectly fine as 4S's Siri.

Do u think Siri is nice additon to iPad or stress up apple servers and delay Siri's response time ?
