As cycle 24 starts to wind down, we're starting to see almost daily predictions for cycle 25 and beyond. This article from last years Nature magazine proposes a promising model composed of a pair of dynamos. After training the model on observations from cycles 21-23 onwards, the researchers extrapolated back in time and have achieved (in their words) 'spectacular' accuracy matching historical data. This is given them the confidence to extrapolate forward to cycles 25 and 26. Very interesting and readable article. (Apologies to anyone that's already picked up on this)
