Pretty high, I would say! The Surface Team typically releases a refresh every 12-24 months. We got the Surface Pro 5/2017 in June 2017, which was about a year and a half after the Surface Pro 4. The Surface Book 2 came two years later from the original release arriving in November 2017. With the Surface Pro 8 and Surface Laptop Studio both being totally new design tracks much like the Surface Pro 4 and Surface Book were back in 2015, they might want to hurry to get those revisions that didn’t quite make the cut for the first iteration in. I think Alder Lake might accelerate that too seeing that the only notable improvement performance-wise (for consumers anyway who never saw the Surface Pro 7+) was the integrated Intel Iris Xe Graphics. With another Apple M series processor update inbound likely for this coming fall in the iPad and MacBooks, I think Microsoft doesn’t want to let their CPU performance to lag for too long when pegged against such competition.
