According to the Buffalo News:
The Buffalo Sabres lost less than 1 percent of their season-ticket holders from last season, and they have a waiting list of about 8,000 names.
The team now expects to sell out all its home games before the start of the regular season...
...The team lost roughly 100 season-ticket holders out of 14,800 in the off-season renewal process.
The Sabres cap season ticket sales at about 4000 seats under the capacity of the HSBC arena and expect such a strong demand when single game tickets go on sale September 15th that most, if not all, games will sell out.
