At present HAL is looking to install a solid dependable line for various units of this craft. The following statement gives us a hint of their goal.
“HAL-ARDC is taking up for development and qualification of certain LRUs required for catering to LCA-Mark 2 version. The first prototype aircraft is slated for built during 2013-14, while series production(s) are planned for induction to fleet which is stated to be taken up in two phases commencing from 2016 onwards.”
Even though work seems to have begun on a war footing by getting a metal mockup ready and they have also floated numerous contracts for various plane parts like composites etc yet the author is a bit skeptical about the HAL's capability to stick to the time line. Not only that but 2014 is also the year in which MK-I is supposed to get operational clearance. Looking at HAL's previous abysmal record this project looks like another one for the history books.
