Eldar reviewed?

Dakka just posted this awesome preview of the June cover of White Dwarf. Not only does it show a new Imperial Tank but it references a "new Eldar Nightspinner"!

Does this mean we'll see a review of some of the Eldar units or is this a splash release? Is this directly linked to the new "Tank Battles - Spearhead" that is due to be released in that month's White Dwarf edition? It's difficult to say, but all we know is that June will be a month to remember! Eldar players already hold their breath.
