General ACCASir tells us Syllabus of P2 and Strategic Business Reporting is same or diff??

There is a post on P2 Forum named "September 2018" which picks up on this that you might want to check out. At first glance the syllabus might look pretty much the same - certainly most of the same topics are there and exam docs (with usual update on current IASB developments). However, the way in which topics will be examined is changing quite significantly with less emphasis on the preparation of consolidated financial statements and more on explanation, discussion and analysis - and with no choice in section B this is likely to seem more challenging.
