Yes, for some phones it takes a lot longer or some never get an update. But I think the discussion here was about how fast can an ICS update come? Gingerbread updates and Froyo updates started rolling out about 2 months after they were released. It took 4 months for ICS to upgrade from 2.3, but about 2 months for Honeycomb tablets. Plus there's the whole issue that manufacturers wanted to renew their skins as well.
