It's not as if Bin Suroor has proven incapable of winning Gp1's though, and I can't believe that there can't have been an excuse for leaving him with Gosden capable of being conjured up.
I actually felt sure they'd leave him in training given that New Approach has been retired. Not only that but when you look at the number of 3yo's who've been his opposition this year who've also been retired (Henrythenavigator, Zarkava, I presume Montamare has gone too?) plus the older horses such as Duke of Maramalde, and possibly SoF and Youmzain the cupboard looks bare. In addition to that, we might also have the possibility that we've got a very poor bunch of 2yo's with nothing really capturing the imagination as a 3yo prospect yet. At 10F's on decent ground, Dubai, the PoW, Eclipse and Juddmonte might have been is for the taking? and whose to say he might not have had a shot at the Arc as a mature 4yo. Whats left? Tartan Bearer? Curtain Call? Frozen Fire? Casual Conquest? or is there a forgotten horse still knocking around? Ibn Khaldun?
