@idustrialrev (the plug-in maker) notes 2 old videos from YAKTV where original Final Cut team member Michael Wohl discusses the development of Final Cut and the future of editing:
'In conclusion, Michael Wohl says "Final Cut will disappear" A must watch. http://vimeo.com/8665513'
It looks like Apple will need more of this because knee jerk reflex (this post included) about reports like Apple to delay FCP-8 till August 2011 “The writing is on the wall” (apparently referring to this). Meanwhile Adobe is running a full court press; see for example Is Premiere Pro outshining Final Cut Pro? and the Switch to Premiere Pro series from Chris Fenwick.
Update: Chris Fenwick's series is good, but does show the difficulties in switching between apps with only slightly different UI models; see comments to his video on mistakes in 3 Things Premiere Pro Can't Do.
