I take it your source is the recent Financial Post article GSC?
The same article indicates that that this still leaves, if one were to put ones name on the list today, a wait of over 100 years for your season tickets.

While I cannot find the article, the fact that 24 season tickets were available this past year is a dramatic increase from several years ago, when a mere 4 became available.
The utter hopelessness of attaining season ticket rights may deter a great many from apply or sticking out the ride, but it does not diminish the rabid market for NHL hockey in Toronto. I personally seem to be down to about an 80 year wait.
One year in the playoffs and that list will be back to 10,000 people, a deep run and it will be back to 20,000 people. While admittedly there is your noted factor of the difference between those with the wherewithal to actually afford them and those that want them, the shortcoming is not so significant as to reasonably argue that a point of market saturation has occurred to the point of rendering the financial viability of a second Toronto franchise to be in question.
