How big will the next sunspot peak be?

One thing is certain, experts do not agree! 

In the last few days we have seen quite high solar flux and sunspot numbers for this part of the cycle. Most predictors suggest the next peak will be very similar to the last one.  It could be smaller, but it could be much bigger. Only time will tell.
