Hey, hey, no jinxing the prequel. >:( But yes that is indeed important lol. Generally though Zero series are rather good. They tend to have a different tone from the main anyway since we know that whatever major happens in it leads to events in the main. The difference here is that FT Zero happens several decades ago, and few series do that. So Mashima will dwell into mysteries of FT and not just character backgrounds, mainly cause only handful characters from the Main will be in it.

I think the biggest interest is the unknown founding member of FT. I'm curious as to whether he died(either of natural causes or battle) or whether he will appear in the main series. Sure will add impact for people that followed Zero since they had probably gotten attached to the guy.
