I tried the predictions exercise last year, let's try again ;-)

First 2012 geo prediction: WebGL for 3D portals (or the end of 2d web portals)
Always more 3D data are available. It's now time to publish them and I believe that it's possible to make web portals that combine 2D and 3D. And of course, all this will be supported by HTML5 technologies.

Second 2012 geo prediction: 4D
The world is 4D, GIS data, too.

Third 2012 geo prediction: OpenStreetMap will have a QA process
Data quality is very important and OSM will, hopefully, defines strong processes in order to deliver data with a known quality.

Fourth 2012 geo prediction: all applications in the cloud
Always more applications will be available in the cloud or will have pricing models based on cloud pricing models. And let's hope that public cloud will be used.

Fifth 2012 geo prediction: big geo data & linked geo data
The amount of geo data is always bigger. Location based services or sensors generate huge datasets. The traditional storage, treatments and analysis processes will have to evolve. Linked geo data are very important in order to make the web "geo aware".

Sixth 2012 geo prediction: mobile, mobile, mobile
Applications and services need to be accessible on mobile plattforms. I predict that the "desktop first" paradigm will evolve towards a "mobile first" paradigm since the majority of users will be soon on mobile plattforms.

Seventh 2012 geo prediction: social geo
Facebook or Twitter have offered recently to geo tag the statuses. This is a first step towards a wider usage of geoinformation within social media. Let's call it GeoSoMe ;-)

For a summary of last year:

YES - Second 2011 geoprediction: always more cloud gis applications
YES - Third 2011 geoprediction: the start of the end of heavy clients
NO - Fourth 2011 geoprediction: clear separation between web mapping and web gis
YES - Fifth 2011 geoprediction: geoservices for all and everything
YES - Sixth 2011 geoprediction: REST, RESTFull and (Geo)JSON
YES - Seventh 2011 geoprediction: WebGL will allow fantastic 3D applications
