Backstage has posted the 4th show at the Meadowlands and second shows at both Toronto and Chicago. Fan club tix go on sale on 4/7 (supposedly at 10:00 AM local time, although I haven't seen that officially yet). I'm seeing news about AEG/radio pre-sales for the shows on Friday, 4/9, and the public sale starting on Monday. Some of the shows have just popped up on TM.
