Porsche's CEO, Matthias Mueller, has put a temporary hold on the several new models like the Cajun and 356 Speedster.

Speaking with Autocar, Mueller said the company needs to "...clarify how we are to spread out our product program - below, above, left and right and so on." He added, "There are a lot of questions still to be answered and we want to create a business case" for production.

As part of the process, the company will conduct a review to determine what models are viable and appropriate. Furthermore, Mueller contends exclusivity outweighs the highly-touted goal of doubling production to 150,000 vehicles annually.

Thankfully, the review will not affect the 2012 Boxster and 911.
