It sure is great news, but i'm not so sure about a TdF winner within 5yrs.. Bearing in mind that Contodor it still young, and you have other established names such as Gesink, Gerderman etc who are a few years away from their prime we would need a rider who's around the 19/20yr old mark now and destined for greatness.
I know there's lots of talented guys out there learning their trade at ProTour teams (Ben Swift & Johnny Bellis spring to mind), but that's a big leap to a Grand Tour champion..
Gonna be exciting to watch though
