Martin MLA and EAW Adaptive are two completely different animals, as others have pointed out.
Having used both, I will say that MLA is very good and Adaptive is even better, especially in terms of coverage adjustments in real time. Both will consistently outperform a lot of traditional line arrays under identical condition and Adaptive will blow them out of the water if you have to fly the PA from a difficult point in the venue.

FWIW

The future of line arrays should be triangular, right?

We started with single point speakers, then moved to lines...next we should be moving to triangular speaker arrays, right?   8)

And then round arrays.

OH wait-some major manufacturers did that years ago (roundish anyway-OK more like a square with no middle-just the outline).  At least in their brochures.

I have never seen it in the wild

It's not a line array, but Danley is almost there with a triangle. Just got to move the sub behind the two Jericho's.

What would be the purpose of triangular?  Line arrays are an attempt to create a theoretical source.  You can have theoretical line sources, theoretical directed singe point sources, or theoretical omni-directional spherical point sources.

A line source capable of concert SPLs will have multiple arrivals from the bottom to top elements.

Going triangular would add another axis where there would be multiple arrivals.

If you were in an anechoic space, a spherical source would give everyone the same FR but not the same SPL.  In the real world, the reflections would make it a non-starter.

So you are left with a pseudo directed point source.  Either by combining elements mechanically or by electrically compensating to give a similar effect.  Each has it's issues.  There are SPL issues with getting enough air movement within the wavelength limitations of a single physical point source, and it is pretty much impossible to eliminate the multiple arrivals of a large virtual point source.

The more we know, the more we realize there's more to learn.

I think you missed Cap'n Smartass Bigler's satire.

Yes I think this is where we are going, processing to maximise the combined performance of the elements in the array.
   
As you mentioned there is MLA and Anya. Recently Martin released a cheaper version using the same technology the Wavefront Precision Series.  d&b Audiotechnik has now introduced ArrayProcessing and AFMG has released FIRmaker which is being picked up by quite a few manufactures. 

Even cost effective speakers such as dB Technologies DVA and VIO line arrays allow individual settings for each box and full computer control with RDnet to maximise their performance.

I hate to put woofers behind the mains.

One big reason is that the woofers are "already late", by the time the sound comes out of the cabinet-due to the delay of the low pass filters etc.  So the mains would have to be delayed even more-which makes them arrive at the listener later.

So they "should" be in front of the mains-but that isn't going to happen.

So putting them on the side is the best option.
