The WKT Raster extension will become the new PostGIS RASTER type in PostGIS 2.0 planned for next april. The PostGIS and the WKT Raster team met at the FOSS4G friday's code sprint and decided that WKT Raster was mature enough to bring interesting new functionalities to PostGIS. A new MapAlgebra function should be added for this release.
