It should work for $K(n)$-local even periodic $H_\infty$ ring spectra. If $E$ is even periodic and $p$-complete then in many cases it is a retract of $\prod_nL_{K(n)}E$. I don't remember what is the maximum generality in which that is known. Using that fact, one should be able to generalise the statement about special subgroups. | |

Because the reason I actually posted this question is that I had convinced myself that something like that is true! | |
