What's the use of voting??!!!

In todays precap they showed preview of performances in Grand Finale. Also in starting when Salman was standing by the one way glass in the kitchen area near sink, no one was visible inside the house. Dosen't that means that Grand Finale happened today morning itself and most probabaly winner of BB7 most likely is announced today itself i.e., in the noon. Then why is BB7 ppl telling us to vote for our fav. contestant till Saturday morning as voting lines are open till morning. If the perfoemances happened today and the winner is gonna be announced tomorrow then it means that Salman went to Lonavla today to perform for Grand Finale and most probabaly all the ex-contestants of BB7 went to Lonavla today to perform along with him and today they all will be staying there itself as it is pointless to travel from Lonavla to Mumbai and back again for the winner announcement. If.so then it means that Salman is celebrating his birthday today in Lonavla by performing with BB7 ex-contestants and celebrating his birthday with them???!!!!

if you notice the shoot of only Salman and eliminated participants is completed...

ok now I understand. So basically they want to finish the shooting of last day of BB7 early tomorrow so they shot all the performances today itself to save the time. Tomorrow they are just gonna announce the winner and wrap up the shooting. So it means that Salman and all the ex-contestants of BB7 will stay in Lonavla tonight, b'cos I don't see any logic of going back home and coming back tommorow again for just thr crowning of the winner as its just waste of time and the travel cud get tiring. So it means that Salman celebrated his birthday today on BB7 sets with the BB7 team and all the ex-contestants that is why everyone from BB7 was there in his birthday party. It means Salman was working today on his birthday too. Poor guy had to shoot for Grand Finale perfomance on his Birthday.

No!

d performances were shot on wednesday, Salman's party way held in Panvel he requested shooting pre-pone for his birthday!
as for finale winner declaration segment, that will apparently b shot on saturday afternoon most likely n telecast sat night!
