This is all part of Aizen's plan!XD

Well apparently, there's a rumor floating around that the anime is in it's last season. The band that does the ending theme started the rumor by saying.....

“I think our tune is perfect for the final season’s climax – please check it out!”

This would suggest an April ending to the anime. Now only time will tell if this actually true or not.

Btw, the comment section is loaded with trolls XD

Bleach's recording director assistant Yosuke Morita confirmed on his Twitter account that the broadcast schedule has been set well into the future, and so the anime will not end soon. Thanks, lemursrule.
