That's exactly what I'm hoping for. We need more competition in the broadband and content delivery market.
More HD channels don't exist (and current ones are shared) partially due to bandwidth restrictions. If a new kid onthe block comes up with a fiber solution, then you can be sure the others are going to have to expand their services (satellites or additional technology) to allow for increased HDTV broadcasts.
In the future when more and more is produced in HD format, it will be a hard sell to broadcast that content in standard definition. Shoudl make for an interesteing next several years.
