Naruto Shippuden : N00b-ish question

[chaos-unleashed]

Is the double ep part of a new filler arc? or has there been a filler arc within the series for some time now? I'd really like to know as i dont follow the manga so half the time i dont know whether if im watching a filler or not lol thanks guys

 

[Ryo Chan]

filler arc starts with the 2nd episode of the double part

The 'Next Episode...' preview seems to suggest that the next episode will be canon, mind.

it would appear that they will begin the training then swap to filler
