I will just copy what the text says on http://us.battle.net/d3/en/forum/topic/16542805071#1

The bolded text is from the post, I did not add it.

We've been thrilled to see so many players actively participating in Season 2 as well as on the PTR for our upcoming 2.2.0 patch. Your feedback has been integral in the great strides we've made towards not only our next patch, but our next Season. As we previously mentioned during our most recent Tavern Talk, we want to ensure our patching schedule provides the best player experience possible while allowing us to provide updates in a timely fashion. To facilitate this, we're moving towards the following model:

End the current Season Launch our latest patch Begin the next Season

We received a lot of feedback during Season 1 that thirty days was too long a time frame for an end of season announcement. For Season 2, we'd like to instead provide a two week notice. At the time of that notice, we will also provide the exact times that Season 2 will end as well as the date and exact times that Season 3 will begin.

Please note that this post is not the two-week warning. While we don't have that information to share with you today, we want those of you participating in the current Season to know what to expect moving forward so you might plan accordingly to meet your Seasonal goals.

In the meantime, we wish all Season 2 challengers the best of luck, whether it’s knocking out a Conquest, putting together your perfect set of gear, seeing how high you can get in Greater Rifts, or wherever your adventures may take you.

Ok so...

Please note that this post is not the two-week warning.

not the --- warning.

not

There is nothing that says Season 2 is ending. On the contrary the post states that those participating in Season 2 should keep moving along with their current goals. That implies to me that this post is not saying that the season will end soon.
