I'm guessing they won't, as the trackballs are more generic and didn't have the FIRST name on it like the tubes did, so it can be more easily sold. Also, the price of the trackballs were $80~$100, vs $5 for the tube (original price). Even at half off they are still pricy. And the quantity of trackballs were a lot less per "field", and more durable, so there were less of them to begin with.

But the original Bldg 19 tube ad came out around this time last year, so sit tight and wait for it!
