1) Reality Sites
2) Multilingual Tours w/ Geotargetting
3) Companies becoming more and more professional
4) Front ends with less lies. IMHO Companies that want to claim more than they really offer should be punished in some way.
5) The average gallery maker will make less and less money
There are zillions of trends... some become the next big thing, some stay in ideal worlds... but those 5 are very likely to become reality in the near future.
Take care,
