Al Jazeera quotes Ali Nourizadeh on the bills before parliament. (Actually, a groups.google.com search shows this is from March 24 or before.)

“The hardline Council of Guardians will not approve those laws,” Zadah said. “Khatami will then either resign or call for a referendum – which is what Washington wants – since the majority of Iranians want a change in government – a secular one and not Islamic. If the US is in Iraq, you can expect rapid changes in Iran.”

I agree with the part about the GC, but not the bit about Khatami. I think the Economist Intelligence Unit has it right.
