I'm good with a small global tour. Something like 2 shows in London, and 2 more in the biggest cities in the UK. One or two in Paris (depending on demand). She can do one or two in Germany, Switzerland, Denmark, Finland, Norway and maybe the Netherlands (but she can skip NL cuz she hasn't been doing too well there AT ALL), Russia, Portugal, Poland, Czech Republic and Spain. Then 2 or 3 shows in Tokyo and some in China (Hong Kong, Shanghai). If she really wants to get big go to Malaysia and Vietnam and possibly South Korea. NO Latin America (sorry Antonio, I will NOT have to 30% filled venues).
No Australia. It's a great touring market, but it costs too much and God knows what'll go down after Circusgate in 2009. What worries me more is the venues, though. She can't sell out stadiums and even arenas are doubtful. I'd hope for her to stick with 8K - 12K capacities.
It'd be cool if they did PoM WW and just combined the NA gross (Vegas) with the WW gross for a 100M+ grossing tour.
EDIT: And definitely some in the Middle East (Abu Dhabi & UAE)
