goldman ups it's cu forecasts

Did anyone pick up on the latest of the Cu price upgrades? Goldman cranked up 2010 to a smidge under $3.50Lb. I don't speak to anyone there but would be fascinated to know what their long term assumptions now are.
It is worth noting that Industry still has very low assumptions on the Cu pricing going forward - $1.80Lb seems to be a commonly used number. Whether or not this is due to their being conservative in their own internal assumptions or whether they just want to suppress the mkt to suit their own needs is anyone's guess but ------ I would be fascinated to see what would happen to the sector if they started to use numbers that were somewhat higher to recognise shortages going forward. Happy days for the likes of IRN if that proved to be the case.
