I expect the iPad, lacking any new revolutionary functionality, to reach a steady state of (new customer + replacement rate) sales that is some percentage of its peak, pre-saturation sales. If replacement rate is every 4-5 years, this may be below 30% of peak.
This won't mean it isn't successful, just recognizing that existing users don't need to upgrade every year.
