Hardly. Jay has a Good Friday rerun. Dave is usually off next Monday for NCAA Night, then takes his annual birthday vacation the following week. The Late Show is only taping two nights next week, so it may be new shows on 2/3/4 nights, depending on whether they double-up. Guest lists haven't posted yet. Each has new shows for Sweeps (April 29 - May 26), then Dave is off for 10 days. Dave will continue to take 10 weeks of vacation a year. Jay will continue with less than five weeks off. Jay will have NBC-Universal stars on 3-4 nights a week to cross-promote. Dave will continue to get the major movie stars and random celebs. In other words, the same as usual.
