My primary concern is that Universal just opened a 360 attraction last year, and now they're essentially pulling a Transformers and adding the same attraction again, just with a different theme (and, based on what we've heard so far, in much less impressive fashion). Strikes me as not particularly the best move for the diversity of USF or UOR as a whole, to say nothing of whether or not that approach best serves the F&F theme (and it doesn't).
Will I go into the attraction with an open mind? As much as possible, yes. However, I cannot foresee a scenario where I'll walk out of the ride thinking it was worth replacing Earthquake/Disaster for it... unless everything we've heard about the ride is incorrect.
