May's equivariant Landweber exactness conjecture

Let $E$) be a Landweber exact spectrum, let $A$ be a compact abelian Lie group, and let $MU_A$ denote equivariant complex cobordism for $A$. The relative smash product $MU_A\wedge_{MU}E$ is an $A$-equivariant spectrum. May's equivariant Landweber exactness conjecture. If $E$ is a Landweber exact spectrum, then $MU_A\wedge_{MU}E$ is an $A$-Landweber exact spectrum. The conjecture is known for $E=BP$, while $A$-Landweber exactness of $KU_A$ does not establish it for $E=KU$.
