I predict in 5 years ...
1) There will be a larger audience viewing and clicking on adsense ads
2) There will be more advertisers advertising on adsense
3) There will be more publishers
I think a key factor is if the monetization of advertising will improve by both google and publishers increasing the effectiveness of the medium for advertisers
