I don't expect them to sync exactly, but in the past the numbers have shown roughly the same --- Adsense might say $100 earnings while Analytics only tracked $90 of those earnings for example. Not a big deal. But the discrepancy is now much larger, dropping to Analytics only catching about half the earnings last week and now only about 1/3 over the weekend.
In some ways, it doesn't matter if the overall numbers sync, but if you're interested in checking earnings by page and you know you're only seeing 1/3 of the total earnings, you really have no idea which pages are performing better, because there's no guarantee that the few results you are seeing are even proportional --- I might be seeing all the earnings for one page that actually earned less while seeing none of the earnings for a page that in reality earned more.
