I hope somebody gives a review pretty soon. I have to admit that the console paradigm is what's got me interested. I live in console view with Sonar and never bother looking at the track view for more than 1 track at a time.

Already posted, I had problems with it, crashing-lock ups.
I'll use it more I'm sure but it besides a few new features it reminded me of the old version.
 

The custom meter feature in ardour 4 is nice. I use ARC 2 and with the custom meter I can place the metering before ARC 2.

I'm intrigued but cautiously hesitant to buy into the hype. I bit on the previous version and my conclusion was that it was a stripped down version of Ardour with a very nice saturation plug-in. The workflow to take advantage of this plug never seemed worth it to me.  Initial glance at this still seems to indicate a 64-bit stripped down version of Ardour with interface tweaks and a nice saturation plug. It just still seems like one could simply dig through saturation plugs until a pleasing one was found. I suppose $40 isn't that big of a risk, but $39 didn't seem like a big deal either until the product felt useless. In so ways, full version of Ardour might provide more bang for buck. Maybe one day I will hear something that sounds so overwhelmingly better in terms of sound that blows me away, but I sometimes supect placebo effect.

I look at it as the full version of Ardour with the added features and function of Harrison Mixbus. If nothing else, for $40 you get some very nice console emulation, eq's, comps and tape sims.

Just got the email...you can get MB3 for $40 or MB3 with the XTC-LC for $99

That's their new Look Ahead Compressor Plugin...normally $109...

While I would REALLY like to buy this RIGHT NOW
I think I'm going to opt to wait this one out...

They notoriously have sales...so when the smoke clears..I'll see where it's at...
It's not a necessity for me and money is tight...so think I'll hold on to my 
pennies for now...especially in light my current situation...so...keep me posted!

I just received the email, just wondering if anyone popped for the XTC-LC comp also.  Any thoughts?

Judging from their other XT plugins I'd say it will be decent...

The XT-LC Lookahead Compressor is a compressor that works when others won't. Its lookahead design, with super-fast attack and release properties, makes it able to do things that a regular compressor can't match. Zero-History^(tm) release time allows the XT-LC to be used aggressively on very dynamic sources (such as acoustic guitar) while still maintaining a transparent release character.
The XT-LC Lookahead Compressor features very simple controls: Threshold, Ratio, Knee, and Makeup. But don't let the simplicity fool you. This is a very powerful tool for professionals that have tried everything else.
 
Features:

• Advanced "lookahead" compressor algorithm.
• Ulta-fast attack and release times with Zero-History^(tm) release.
• Calibrated Input & Gain Reduction meters
• Threshold control
• Ratio control
• Knee control
• Makeup Gain control
• Momentary Bypass switch

Yeah! Just got my email too! Trying to decide whether to just get Mixbus, or get the XT-LC too for $99.

I just noticed something else on the Harrison website:
 
The initial release of Mixbus v3 is shipping with control-surface protocols disabled.
An upcoming release will re-enable the control protocols, which include MIDI controllers, Mackie fader protocols, and OSC ethernet control.
 
Guess I need to give them a call Thursday because if I can't use a MIDI controller (keyboard) it would not be very use full for me. I am also going to ask about the existing plugins I have already purchased, will they work with the 64bit version or is that an additional cost.
 
I do think I will pass on the extra $60 for xt-lc comp. I just can't imagine that I don't already have something similar already...
