Not using the sim to promote their own planes is, in my opinion, a huge misstep on their part. When you can download and install a reasonably close (no not close like it was designed by an aeronautical engineer or anything) representation of a Horizon model in a competing simulator months or years after the actual aircraft have been released I would say that's pretty much an admission of, if nothing else, that they don't believe the sim is a valid marketing tool or they don't think they'll get enough market penetration with the product to compete against the currently dominant product(s).

I love the sim, they need to invest in it.
