Brighter, yes, but not very bright. The density of stars will not increase very much. Currently, to see the Milky Way, you have to be out in the boondocks, far from cities and other light polluters - the thing is just so faint.
After the merger, perhaps it will get brighter, but the increase will not be spectacular. The brightness of the combined galaxy as seen from Earth will be dictated by the stellar density, which will not change much.
