They will only start deploying FTTH everywhere when Bell gets more aggressive with deployment, otherwise, they couldn't care less.
Aside from Bell Aliant's FTTH footprint, Bell's FTTH footprint is pretty small and is comprised mostly of new builds. Rogers has also been deploying FTTH to most new builds, but they're using DOCSIS based provisioning, hence why there hasn't been much buzz about it. However, if Rogers wants to create new service offerings in those areas they just need to swap out the customer premise equipment. In addition, DOCSIS has enough life to compete with FTTH for the foreseeable future as long as the network is managed correctly. For Bell, copper is already being stretched really thin, so they have no choice but to be more prudent with FTTH.
