Bleach anime is not going to end: we'll have fillers until the new arc begins!

The calendar for Bleach episodes in March hints that we're going to have a fillerology ala Naruto before the new arc post-timeskip begins.

How much will this fillerology last? 3 months? 6? 1 year?


311"The Soul Detective・Karakuraizer Takes Off Again!"
"Tamashī no keiji・Karakuraizā sai hasshin!" (魂葬刑事・カラクライザー再発進!) 
March 1, 2011
312"Inauguration! The Brand New 2nd Division Captain!"
"Shūnin! Arata naru ban ni ban tai taichō!" (就任!新たなる二番隊隊長!) 
March 8, 2011
Could this be true? Or is this a distraction to throw us off?
