More weekend buzz on Tesla Motors (TSLA) (previous): Shares will be on watch Monday following a Barron's cover story that pitches the case that a triple-digit share price is unjustified. Two things to consider for the EV automaker's long-term potential: 1) Will the cost of electric batteries come down as Tesla rolls out its Model X and Gen III? Opinion is sharply divided. 2) While CEO Elon Musk says he sees sales reaching 30K-40K per year soon, if you crunch the numbers it appears investors are betting on sales reaching a level of hundreds of thousands a year. Despite Tesla's transformative tech, as the company eventually enters the mass-market segment valuation could fall back in line with peers.
