Hi Gergely, I do a lot of predictive modeling, and the approach I take is to export my data (prepared in GRASS GIS) to an open-source modeling software such WEKA, and then map the results using GRASS. It takes a little more work than utilizing built in modeling options often found in GIS software, but you can do a lot more with it... For GRASS this entails exporting your variables (rasters I'm guessing) as single column and combining them into a csv file which you pass to WEKA. Then you map the results of your predictive modeling in GRASS. If you want more detailed steps I could help you out, but my suggestion is to just play around with it to see if it'll work for you. I'm writing a program at the moment which couples GRASS and WEKA, but it's still in a very beta state.
