Whatever he does, co-design with Donatella at Versace is not the way to go. It doesn't work for Raf and Miuccia and it probably wouldn't work in this scenario either, it's simply not a good idea.
I always loved Tisci's Givenchy and loathed everything he designer for Burberry, despite similarities to his tenure at Givenchy. I'm hopeful that wherever he eventually ends up we see the same spark he used to have at Givenchy. I don't mind him consistently casting the same friends, as I personally love Mariacarla and Irina and most of his celebrity associates, to me it felt like they were a great extension and representation of his vision - especially MCB at Givenchy, she was perfect.
Oh, and I truly hope that whatever he does next does not rely so heavily on logomania. It looked so utterly ugly at Burberry.
How come he doesn't design under his own name, though? Is there any specific reason? I seem to recall seeing a Riccardo Tisci collection once upon a time, in my memory there seem to be wooden crosses on the set. What happened to that?
