From what I was told by a couple of dealers the F142 launch has been put back from 4th quarter 09 into the second quarter of 2010 though no firm dates have been set AFAIK. They are not aware of plans for any revision of the F430. It certainly wouldn't make much sense to change the current engine in the 430 for the new DFI unit set to appear in the F142 as that would steal the new cars thunder somewhat. I suspect that the marketing department at Maranello are counting on the California to be a hit next year and have calculated that the Scuderia coupe and forthcoming Scuderia spider will provide enough sales to keep the 430 production line busy. The Scuderia spider is due to be revealed to prospective customers at the Ferrari World Finals in Mugello next month I understand.
