I doubt if crosslinking would be your real culprits. I got 5 websites that still maintain crosslinking with one another by 100% and the rankings are still fine up-to-date and this has been nearly a year now (although they had to weather the storms of Florida, Brandy and missing index page). The only problem that I see is that there is not much PR boost (or PR transfers among the sites are heavily discounted), however, it seems to be good for visitors to get quick access to the desired destination.
