Recently proposed exceptional field theories (EFTs) making manifest theduality $E_{n(n)}$ symmetry, first observed as nonlinearly realized symmetriesof the maximal $d=3,4,...,9$ supergravity ($n=11-d$) and containing 11D andtype IIB supergravity as sectors, were formulated in enlarged spacetimes. Inthe case of $E_{7(7)}$ EFT such an enlarged spacetime can be identified withthe bosonic body of the $d=4$ central charge superspace $\Sigma^{(60|32)}$, the${\cal N}=8$ $d=4$ superspace completed by 56 additional bosonic coordinatesassociated to central charges of the maximal $d=4$ supersymmetry algebra.  In this paper we show how the hypothesis on the relation of all the known$E_{n(n)}$ EFTs, including $n=8$, with supersymmetry leads to the conjecture onexistence of 11D exceptional field theory living in 11D tensorial centralcharge superspace $\Sigma^{(528|32)}$ and underlying all the $E_{n(n)}$ EFTswith $n=2,...,8$, and probably the double field theory (DFT). We conjecture thepossible form of the section conditions of such an 11D EFT and show that quitegeneric solutions of these can be generated by superparticle models the groundstates of which preserve from one half to all but one supersymmetry. Theproperties of these superparticle models are briefly discussed. We argue that,upon quantization, their quantum states should describe free masslessnon-conformal higher spin fields in D=11.  We also discuss some relevant representations of the M-theory superalgebrawhich, in the present context, describes supersymmetry of the 11D EFT.
