Hmph. I am a bit confused.
26 is supposed to be another AOI style 3 part episode and generally those are non canon, does that mean that 25 is then the series finale? (I thought it was generally assumed that because we haven't yet heard that the show is confirmed for another production season that the last episode is the series finale but left open ended - like TDHAIP or ITWGY.)
Does this mean that:
25 is the series finale in canon and 26 is a non canon thing like the Holiday Spactacular
26 is the series finale and it is also canon and still in a 3 part style
Either way seems a bit strange, especially if (I hope not) Futurama doesn't ever get renewed again and 6ACV26 is the last Futurama episode ever.
