Will there be a stimulus round two?

Interesting observation by Richard Wolffe last night on Countdown: he suspects (presumably from background conversations) that by the second-half of this year, there will be a second round of stimulus spending.

Of course, this could just be a notion floated to ease concerns among some that the current stimulus package isn't large enough. On the other hand, six months from now, if the situation hasn't turned around, there will be demand for additional stimulus spending.
