Will the Chargers be the next to leave Qualcomm

With the 49ers leaving San Fran and Candlestick park, do you think the city of San Deigo is going to pony up the money to build the Chargers a new staduim if they do indeed threaten to leave like the Niners have.
It would be a shame if the Chargers left becuase their a good team now with LT and Marty Ball giving them some power back in their team this season and in the past with Brees when he was their.
As you may know, Qualcomm is nearly 40 years old and is way past its prime as a legitimate staduim compared to newer fields like Detroit and Houston, would they follow the Niners leave and think about leaving San Deigo?
