I have read Eoin's Artemis Fowl trilogy and found it quite good -- but it's not anywhere near the same writing style used in Hitchhiker's Guide. If they wanted the same Hitchhiker feel they probably should have gone with Terry Pratchett (though I doubt he'd accept, he seems to quite enjoy his own Discworld universe). I'm sure it will be good, just different from what people expect from the series.
