I would prefer to keep it the way it is for three reasons
1 Like you mentioned, it would take away a little attention from the upcoming event.
2 People would get a lot of credits tied up in fights 6 months away, and they wouldn't have any to bet on the prelim fights when those lines come out.
3 The lines often change considerably from when they open, so either you're going to have to change the lines a bunch or we have crooked lines from time to time.
Just my two cents, not a big deal either way.
