WHAT IS WRESTLEMANIA 26 Signature? or tagline?

ive been notice that wrestlemania every year has a tagline or signature below.. such as wm XX (where all begins again) wm 21 (goes hollywood) wm 25 (the 25th anniversary) etc..

but yet wm 26 has no tagline.. and it just wm XXVI..

what do u think guys??
