I can also confirm that all of my FeedBurner feeds no longer show the number of subscribers. The feeds are still displayed, but statistics appear to be gone.
The FeedBurner Status Blog has a very minimal post acknowledging the issue: [feedburnerstatus.blogspot.jp...] Good to know they're working to resolve the issue, but it has been almost a week since I've had stats.
Time to look at alternatives I fear...
