According to the Agena newsletter, they are expecting a shipment of ES eyepieces on Monday (25 Feb) and should be able to start shipping on the 26th after inspection. The models they are getting are the ES 82° 4.7mm, 6.7mm and 8.8mm; plus the 9mm 120°. They state that after filling backorders they expect to have a few of each left, though the 6.7mm 82° is almost gone again. So they are accepting additional orders on these (the "backorder" button is active). So act quickly if you are looking for one of these.
