I went to an apple store in my town here in The Netherlands and one of the workers (well actually I think it's the owner but I'm not sure) there ensured me that there weren't any updates coming for the iMacs for the next six months, at least. To me this sounds a bit off, considering the current iMacs have been around for a while now. However, who would purchase another iMac there if he told his customers there'd be a new iMac within a few months?
