I own the vs system, think of the VS-700C as the hardware translation of Sonar 8.0.
This was the golden age really. This was fast, intuitive and awesome.
Then came 8.5, (also awesome) and X1...
Understand that X1 was nice also. We had some problems with the EQ layout (which don't line up with the labels on the console, still today) but that was not a real problem, just a deception for us who though we got the ultimate in Sonar integration. Other bugs were related to the new software codes and were not vs specific problem for the major part.
Then Prochannel modularity (X1D) introduced a latency on the display when banking through channels/busses, not the end of the world but a general "not again" reaction from users.
Some others bugs/functionnalities were still not adressed since Sonar 8 (like x64 Fatom editor and some others) and we, users, started to feel like an after-thought, a dead weight on Cakewalk shoulders and continued to try to convinced ourselves that we didn't invested that much money on a sinking flagship.
Some of us became less prone to wait and the tension raised on the VS forum, asking more and more for Cake's attention.
Then came X2. Ouch. If you try to control the Prochannel with the VS-c channel strip, 2-3 moves on the knobs and the C display will freeze and act funky, the snap button freeze with the 2nd press and I successfully freeze Sonar when using a combination of the above while banking through tracks and busses 100% of the time. It's the first time the channel strip/prochannel is that much broken. And, no improvement/feedback on the features we wished since Sonar 8. Also, if you press the automation button to write one, all, I mean ALL availible parameters will apear on an automation lane, that mean around 25-30 lanes are created just to write a volume automation...
Now, some of the users feel rubbed, so if you took a look on the VS forum, you'll understand why the general tone is somewhat harsh...
THAT being said, Ryan Munnis is very kind and pop on the forum here and there to do what he can to explain what is going on and what they are investigating. I believe that Cakewalk will do what they can to keep the VS afloat but the update will always go in this order (according to what we experienced so far).
New version of Sonar/patch -> some month waiting -> VS-700 update patching what the
hardware permit I would like both beign done and released at the same time but it's not the case right now.
Note that once the Channel strip section/snap setting are fixed, there's still A LOT going on in this surface that goes WAY beyong the Mackie/ Protools functions. A quick look at the manual will show you this.
I would say wait for X2A and make your decision once there. If you decide to get it even if the support is not yet availible, then watch the used market since there will probably be some VS system on ebay for cheap lol.
Beside all those drawback, the VS combined with the VS-R is still an awesome sound machine that compare favorably to higher priced soltution. Also, controlling the VS-R gain and etc with the faders is very a addictive feature and it's limited direct monitoring functions can be cured by adding the octa-capture for a serious amount of I/O. By the way, I use the Fantom and the ARX-01 x64 on every project and they sound perfect. Patch selection in the Fantom is tedious though and the bit bridged editor sometime screw the automations.
RME is very nice, but so is the complete VS-700 package.
