length of updates for Enfold theme

Hi, I am trying to sell a client on using your Enfold theme for their latest site redesign. On Themeforest it says the $60 fee gives:

Included: Future updates
Included: Theme hosting offer
Included: 6 months support from Kriesi

The client knows he will need to pay for extended support, but are theme updates unlimited after the initial purchase, or will another license/subscription fee be necessary after some period of time? Thanks!
