Of course.
The changes to new versions are subtle and take careful critical listening to determine differences. I've heard the v4 series and unless i had them side by side with a switcher, good luck telling a difference.

I was contemplating moving to wood veneer possibly in having to buy a VP180 and an EP500 so there was a thought to trade in the M60s for newer versions in wood veneer or as i mulled, going with omnidirectionals. This is way down on the list of needs though. In fact it's a possible 'want' and not a need.
What we need first is newer AVR, tv, centre channel, amp...
