More than 4 updates for Ubuntu 12.04.x for LTS versions

The release schedules aims 4 release for Ubuntu 12.04. The problem is that 4 versions concerns 2 years, instead of the 5-years support. I think a lot enterprises would want to stay on this LTS during the whole support period. Newer hardware, newer software will come. That's why I think Canonical will have to release more than 4 releases. It seems to me that 8-10 releases is a good idea.
