Is it Venkat/Nisha ???

The wild card round 2 trailer was telecasted in Vijay TV yesterday... They were showing performances of Venkat/Nisha and Sangeetha commenting that the performance should have been done in the finals.. she meant that its so good. Aishwarya Danush went onto stage to congratulate them.... But there was nothing shown about Rajesh/suhasini :(
I am waiting to know whats going to happen in this case.. will Venkat/Nisha go thru to finals or someone else.. Eager to know the voting status even...
