A forum member recently posted info he received from an enTourage admin that they've had a significant setback with regards to a third party software partner after bmoc's original post.

I think we should prepare for an April release, maybe later.

As for if both devices will get it, the original "A statement about Froyo" post by dontpanic indicated they were finding it easier to update the PE than the EE, and therefore the PE would get it first. I would continue to assume this, although if we're lucky enTourage may get the update ready on both devices at the same time.
