Incompatibility with older wheels and frames, hoping for business from forced upgrades.

Increased rigidity is the main benefit.
There is also some concern that the braking power and action of disc brakes could result in the wheel being pulled out of some dropouts if the QR isn't tightened correctly (which anecdotally happened a few times when the mtb standard was quick release), a fear that is eliminated with thru-axle.
The "reason" for the change? Well as Marin says it's likley to force consumers to buy new frames/wheels etc...

I actually had my front wheel come loose many times before I swapped the skewer to a boat anchor Shimano. I support the move to Thru-axle for disc bikes. However, I will probably be moving in the opposite direction and getting a canti equipped bike for next season.
TBH it's more a skewer issue than a disc/dropout issue. Properly fitted, functional, quality skewers won't have a problem.
I worked out the end load achievable with a shimano skewer a while ago, and it's *really* going some! (Following the Pinder/Fox case)

I'm using a standard Shimano QR in the rear of my park bike. I'm running a 180mm disc with metallic pads on Shimano XT brakes, and I've yet to "pull the wheel" from the vertical (!) dropouts, even when landing 2m drops etc.
So speccing a proper QR will be _more_ than enough for any road or CX bike.

It's nice with the thru axles for consistent wheel positioning. That really helps reduce brake rub you can get from a slightly offset wheel.
I personally think the stiffness thing is way overplayed for a CX bike though.
Plus, tons of 29er MTB wheels are thru axle now... so it helps with compatibility.
