That article (see below) said that a call to Tesla said that the Model-X SUV service was booked thru mid-May! How does Tesla deal with more bugs that it can handle? Hiring new people that need to be trained simply takes away from existing trained staff which creates more troubles. If the problem(s) are all software, fine but if they extend to sensors (hardware) then there may have to be a recall, etc.
Wall Street is pretty sneaky about such things.
When Henry Ford revolutionized the auto business 100 years ago, all competitors were small fry. Today, they're HUGE (and smart). They will be real competitors when its proven that there is a market for electric cars and they will crush Tesla (unfortunately). TSLA will have led the way and they will make the profits (and so will Wall Street, but not us).
