Crayuft,
No you are not dreaming. 488 is being readied for the Christmas Train on December 4th and 5th (I think I have the dates correct).
John Bush was in town to help look at 483 and 489 to see what should be next into the shop. It appears that after 488, 489 has been chosen as the next rebuild over this winter.
There has been talk that 463 or 497 might be after 489. Sounds like 483 dropped to the bottom of the list.
So if things go well over the winter, look for 484, 487, 488 & 489 for next year.
