According to the Post article referenced in the article here, Verizon plans to continue planned expansion for the next couple years. Expansion is very expensive and I had already read that they are doing better marketing to increase their customer base in already covered areas than moving into new areas. So if you're waiting for them to move into your area there is still a chance.
Sounds like good news for wireless customers as they are expanding their network. Hopefully better coverage and more services offered.
