Summer '06 E-class facelift

[the zacster]

Does anyone have any info on what's planned for this summer's E-class facelift? The pages on the web suggest that the changes will be very minor (and largely cosmetic)...but if anyone knows any more (e.g. spec changes?) I'd be keen to hear it, as I'm planning to buy an e-class estate (280CDI) reasonably soon but might hold off if the facelift involved some significant changes...
