Well sonarman1 - The point is that all this stuff is implemented in Cubase now at this very moment.
You could argue that it "will undoubtedly implemented in other DAW's", but until now it has not. Should you buy software because somewhere in the future it will maybe, if I am lucky, have the things that I want to use now? That's "buying on speculation", and not a very smart thing to do to be honest.
Bottom line - You must compare DAW's on the specs they have now at this very moment, and not what they "might" have somewhere in the future... Maybe.
I personally have chosen Cubase for very strong MIDI implementation. I have simply found no software that does this better. The audio department is far from weak either. You know that Chord tracks also work on audio (granted - on "solo" material primarily, but still handy)? And dragging MIDI loop in a sample track creates an audio loop? For me Cubase Pro has a lot of features that I found very valuable for me.
For instance - I love the Control Room. I can have the master output signal routed to my monitors with ARC 2 room correction (on audio 1-2 on my MOTU Trav) while at the same time output to my headphone (on Phones 1-2) with TB Isone monitor simulation, and output the final mix to file without having any of those plugins interfering with the output to file. This is just an example, because the Control Room can do much more, but you get the picture.
I do not miss ARA that much, because Cubase Pro has his own version of pitch correction called VariAudio. There you can do pitch and time corection, and it works very well and fast because it's integrated. Granted - Melodyne works better if those corrections must be extreme, but that's not very often. As we got Melodyne for free already with Sonar Platinum, we can use it as VST plugin in these extreme cases, but to be honest - I use it seldom.
Granted - Most of the things I am talking about are not present in the Elements version, but that's the case in most "bottom line" versions of DAW software (take for instance Ableton Live Intro that has only an 8x8 matrix, 8 Scenes and only 2 send/return tracks to work with).
