You're at no risk of losing your seats but you may want to commit to a multiple year deal in order to lock in your seat price, this could save you a ton of cash in 2014 and 2015.
I regretted not doing that in September. It was just a leap to commit to $15k considering you never know what the future holds financially. The initial deadline was, I think, September 15th. But doing a search last night looked like they opened it up again. Is that correct? Might do it, since like you said, it could save a ton since they haven't upped prices in ages and the teams sudden popularity and demand for tickets.
