Britney will make between $30-40 million for her show and some of you will just have to deal. She is not getting anywhere near $60-$100 Million+ for 40 shows spread over two years
Celine had to do do between 300-600 shows for 3 years to get $100 Million...
No one at the Palace or PH are banking $100 Million deals right now because just like Briney they are all short/limited engagements, between 30-75 shows for multi-year residencies. The first reports were based off Britney doing a 100+ per year agreements, which she is nowhere near doing
If her show does good and it gets extended than that is a possibility, but just like Elton and Rod, the first contracts are probabtionary.
