June 11 pilot paper

hello, i noticed that there’s a Pilot paper issued for June 11 exams.

why there’s a new pilot paper, instead of the Dec 07 pilot paper like other papers?

There’s a change in syllabus? If that is the condition, will the paper prior to June 2011 relevant to be used as practice question for this coming Dec 14 exams? because i’m about to print all the Q & A and just thinking if the PYQ prior to June 2011, could save on the printing cost.

And does the suggested solutions provided by ACCA need amendments for P3? For example like P2 & P6, there’s a lot of revision and hence, the old answers from the old question, for example June 2010 need to be revised.
(If this is the case, i’m planning to buy the revision kit by BPP to get the most updated suggested answers, if the answers for Dec 07 – June 14 is still relevant, i might just print it by myself)

Thank you
