Season 3 ends in March

[SuperZay]

Q: When will 3.55 and the patch after be released?

Y: 3.55 will be released in February, and the patch after is planned for March.

So only around 1 month left.

Wow, that is 4 months away.

Season 2 is only 3 months, looks like Season 3 is going to end up being 5 months long. With rumors of probably Season 4 to not happen until after Stormblood launch and possible not right away until mid launch that is a hell of a long wait.

Idk why SE couldn't just split up Season 3 to 2 1/2 months and squeeze in Season 4 for the remaining months until Stormblood.

Season 2 was closer to 3.5 months, not 3 months. Season 3 is only gonna be 5 months long if they wait until the absolute last day of March to end season 3.

Looking back at the start of season 3, the date coincides with the release of 3.45, so they'll likely start season 4 with the release of 3.55. Going with the assumption of 3.55 releasing mid-March (14th, perhaps), will mean that Season 3 will have ended up being close to 4.5 months, which is only 1 month longer than the previous season.
If this release date ends up being correct, that means Season 4 will likely end shortly before Stormblood, or right on the release of it, meaning that season will end up being 3 months (mid-March to mid-June)

Preseason and season 4 will certainly end before expansion.
