I agree with the comments. Most stuff is just rebranded anymore, but that I believe is somewhat caused by the fact modelers have set higher standards over the years of what to expect from a product and like you said, there is only so much you can do away from the basic principles. That is also unfortunately what will hold back any spectacular advancedments due to supply and demand. Just like the CPU example by the last commenter. Fact is PC's are about 3-4 generations behind. RC is no different.
