If you're talking about a single year having passed? No. Never under any circumstance
If you mean at some point in the future ( say.... 5 years) I'd look at
(A) amount of updates/impact of updates
(B) cost of updated book(s) compared to how much I have in my budget for gaming stuff
(C) current and expected usage ( ie am I still gaming regularly with this game system edition or expecting to soon)
(D) expected longevity of said updates ( ie will it stay relavent? Will the revisions just get revised again from the next rind of surveys where people say it was too much revision and it broke in the other direction than before, etc)
But that's just me ...
