With balls it is like with anything in life: once you neglect it, it will go downwards. I guess that when you do not take any care of a current high performance ball, which tend to absorp oil a lot, the ball will surely lose pop. These things need IMHO maintenance, more than some "old school" stuff.
But when you prevent too much oil absorption (wiping) and keep the surface free of machine grime etc. with a cleaner after each session, you can keep a ball up for a very long time.
If the surface tracks out, just make a quick surface refreshment, and you should be fine. Oil extraction every now and then also does wonders. Only in the dire case of damage or an unexplainable loss of grip I'd go for a thorough resurfacing job, since you take away surface material (pffft).
I found that any new ball I had could never be restored back to OOB performance, whatever I tried. On the other side, some old treasures of mine like my Traume (5 years old now) are as good as OOB - fellow bowlers asked me in league if the ball was brand new!?
So, keep yourself from being disappointed, and expect the ball to lose its sharpness. It will happen, anyway. These things are not made for eternity.
