There are strong indications that the T failed to actually update pass descriptions/prices before online ordering for January became possible. One of my coworkers claimed to have ordered a 2007 annual subway pass. We'll see how it works out. I don't have a lot of details on the implications for "corporate" passes, since my current system is "buy a pass and expense it".

(Did you notice how, when passes moved to the CharlieTicket format, most of the small print on the back vanished, including the mention of the T slime? The T claimed at that point that, oh no, they had no plans to get rid of it...)
