Mostly everyone knows "The Teleport Rock" shouldn't warp you cross continent and I would very much like a clear answer if this will get changed. A lot of people holds quite a few of these and it would be a bit unfair not letting everyone know this beforehand. I don't think this has the need to be changede, cheap TP rocks is a good income and a good way of moving around for everyone (no one likes walking) This is the Teleport Rock.
It's probably already changed for the new source, based on Matt's reply when this first got reported in the shoutbox and based on private conversations I've had with GM's before about teleport rock useage. Of course I can't say for sure that they will, but I did get told by a gm not to stock up on too many rocks since they would possibly get fixed.
