Its very hard to find information about the NJ OTB's. But I did get a little info, directly from corporate headquarters.
Penwood has the right to develop 4 OTB's, as we all know. Those 4 will be located in these 4 counties: Camden, Middlesex, Mercer, Ocean. Being from Jersey originally, I know these are all very densely populated counties and should be excellent locations. I don't know why, but I was thinking at least 2 of them were in much less populous southern Jersey.
Penn says they are in early stages of developing a business plan addressing how many to build, where to build, etc. and can give no timetable for opening.
