Tracey Emin, Vic Reeves, Peter Blake and others contributors?

This article from London Calling suggests a number of contributors to this years sale.   They include
Tracey Emin, Zandra Rhodes, Paul Smith, Christopher Bailey, Peter Blake, Jim Moir, James Dyson


Jim Moir is of course better known as Vic Reeves.  Tracey Emin, if this article is correct, hasn't contributed to the sale since 2011.  Her return would be very much welcomed.
