If you look at it, the highest/fastest which is really the granddaddy of the records is on hiatus if not gone industry wide. It jumped from 300' to 400' feet so rapidly and in a fashion that wasn't considered successful for the parks - so unless there is a new approach to 400' out there, I'm doubtful we'll see it pushed. Why push much higher than 300 even (see I-305, Leviathan).
Beyond that, records can be considers either relevant or irrelevant to enthusiasts, marketers, and GP so that is what you get in today's world.
What I'd assume is more relevant is a ride type master plan for a park that looks at the desired customer base (families, thrill seekers, and likely a bunch of other categories), and evaluates the different ride experiences (terrain, twisters, loopers, family fun, high G, airtime,betc...) currently available in both flats and coasters. From here - pick what makes sense for the next 1-3 additions and go look for options - if one of those options happens to be a potential record breaker, then it becomes part of the analysis at that point.
