I think history is pretty clear that there are very few people (like, maybe a couple) who have shown they can predict the market accurately over any type of extended period of time. So I definitely don't pretend to have any reliable prediction.
That being said, I'm definitely anticipating a downturn. It just doesn't change my investment plan (invest in index funds over time and hold 'em.) It does get me a little excited, though, that stocks are going on sale while we're in the accumulation phase of life!
