It's probably old news that Shankar and Vikram will be coming together for a new movie, tentatively titled Therdal. Shankar has readied the script and is scouting for producers. Rumor has it that Aascar Ravichandran just might take the project up in his hands.
But the next big thing would be heroine hunt for Therdal. Shankar is keen on a Bollywood presence and hence is hunting for someone along the lines of Priyanka Chopra. According to industry speculations, Asin is also in consideration. If all goes well, we will get to see Asin in Shankar's Therdal.
