"Lets not forget that this is "Mikes" ( a train guy)s control system. Legacy is owned by investors who have no interest in the products they sell outside of the profit in their portfolio.
Mike makes trains, Guggenheim makes money."
As far as I know this is incorrect and unfair. Legacy was developed by Neil Young, Lou Kovach and Jon Z, amongst others. These guys have their own layouts in most cases. To my knowledge, no one has ever reported Mike Wolf having a layout in his own home 
.
Amongst the current key players, Ryan K and Dave O are clearly train guys. Ryan is particularly knowlegeable about prototype, as you will have seen a huge library of train books in his office. To my knowledge, there is no equivalent amongst the current various MTH principals, although I'm not certain.
The inability of Legacy to control DCS/PS2-PS3 locos in command mode is a legal obstacle, not a technical obstacle. Prior to licensing DCS to Atlas, MTH had refused to license it to anyone else, and indeed had threatened legal action to anyone who wanted to develop emulation software/hardware. Maybe things have changed.
