New collector’s edition owner

This might be a stupid question, but I was curious if the e-voucher is kind of pointless for collector’s edition owners?

I realize that stuff gets released, but if you operate like most people and update every few years you’ll get what you already bought in the end wouldn’t you? I mean I guess it would be good if something came out that would help on a project that you were working on at that moment.

thanks if any collector's owners can answer this most likely stupid question.
