It's been removed now, but Nikon Rumors says this screenshot from a supposed Nikon D300S was briefly posted on Nikon USA's site earlier today. There's not much to go on here, but that SD icon in the corner seemingly implies the update to the D300 will somehow feature an SD slot -- whether it's in addition to CF as previously rumored is obviously up in the air. Either way, it seems like we'll find out soon enough -- stay tuned.
