Peugeot 5008 - Update of model/ - Dickm

I am in the market for a new car and comparing the Citroen C4 Picasso diesels (recently released) and the Peugeot 5008. I am surprised by the differences in VED cost - it seems the C4 Picasso has changed engines and got down to Band B in some examples yet the 5008 diesels are much higher. This suggests the 5008 may be revised soon - has anyone any 'inside information' please?
