That's very good news. It will be a significant boost to the QGIS 
feature list.
As for GDAL, I'd expect you will want to add the support for ECW and 
MrSID directly thru GDAL, not as some separate image support library. Or 
maybe I don't understand something?
In any case, GDAL offers its own toolbox which is useful outside of 
QGIS, and it would be best, in my opinion to have ECW and MrSID support 
"right at the base".
