did you guys (Raoni obviously did) see the post by CAE on facebook? in which he shows the rack systems he recently built for The Edge... contains two AXEFX's, Korg SDD3000 and a BOSS effect and an ibanez..................

and I think what Raoni was trying to say is, that from a "business continuity perspective" a band like U2 can't rely on equipment that is breaking down all the time. I wouldn't be surprised if the Edge keeps on trying the current latest effects like he always has... its just that the effects world and amplifier world are converging markets... just like radio and mobile phones and voice and data...
