Yeah, what about that laughable Avid Orchestra?! I think the previous Sibelius Sounds are at least comparable, and the GPO4 for which I paid ~€85 and use with Sibelius 6 is certainly superior. I hate the even more 'WIndows' look and menus of the current instalment with much "busier"/distracting GUI than before, but I agree with FredB regarding the CC lane, and was expecting many more intuitive sequencer features in this instalment (especially with the AVID aquisition), but the sounds are the biggest laugh... I think they're going to get anihilated by those Finale 12 will probably feature. AVID should have attempted a better integration of the available professional orchestral libraries with Sibelius, rather than just give the mixer a vertical rotation. But what can one expect from people who musically backed the introductory video with a Band-in-a-Box track for a professional and sophisticated notation package, instead of featuring a symphonic movement; who do they think they're addressing? But I suppose with sounds like that, Band-in-a-Box was the better choice...
Will I upgrade? Not right now, I've always been a Sibelius man, but now I think I have to wait and see what Finale comes up with and their cross-over prices.
