The Mummy: Future Sequels

I have read on Wikipedia that they will make a at least 2 more sequels, one will involve the Aztecs (note that at the end of the third Mummy movie, Jonathan leaves for Peru and then its said that mummies were discovered in Peru soon after his arrival)

Personally, I think that one of the Mummy sequels would involve Stonehenge and some kind of European Mummy

Brendan Fraser happens to be one of my favorite actors, so I will be keeping an eye out for a 4th Mummy.
