Version 5 was exciting because it added V-Vocal and PerfectSpace
Version 6 was exciting because it added AudioSnap
Version 7 was exciting because it added sidechaining and the step sequencer
Version 8 was exciting because it added Dim Pro, Channel Tools and exclusive solo
Version 8.5 was exciting because it improved all of the above, and added a bunch of plugins
Version X1 gave us ProChannel. Sorry, that would have been exciting 5 years ago, don't need it anymore. Ditto for Studio Instruments. UI changes, bleh, nice but not necessary and certainly not exciting. All the keyboard shortcuts you've used since Cakewalk 1.0 have now been randomized - uh, OK. Not exciting.
So what's truly exciting in X2? An automatable spectral editor - that has potential but could also end up a toy that we lose interest in quickly. More ProChannel goodies - still don't need any of it. Full Rapture? Hardly ever used LE in 5 years, so the full version probably won't get used either. Breverb? Nice, but don't need it. Console emulation? Snake oil. That leaves TH2 as the most exciting addition.
It's not that these aren't nice enhancements. They are. Just not particularly exciting.
