I took the GMAT a couple days ago and I was one of the integrated reasoning guinea pigs. After the test I sat for another 12 questions in the new format. They had two basic types:
The first is an elaborate decision flow chart, resembling a complex snowflake or some wacky molecule. The questions were about following the logical flow of the chart, like "If [A] then, [B], [C] or [D] etc?"
The second type looked like a reading comprehension thing, with text on one side and questions on the other, except instead of a 3 paragraph block of text, there was just a few sentence introductory blurb, and then other tabs you'd click on to reveal tables of data. The questions were all about reading the tables. Interestingly, these questions had a calculator to use within the software, since many of the questions boiled down to "which row has the following ratio between column A and column B."
Basically, the questions seemed to be testing PowerPoint and Excel literacy, respectively, which I guess is pretty pertinent to the modern B-school curriculum (certainly moreso than dastardly data sufficiency inequalities about the absolute value of various unknown variables would be)
