Kev - that is nearly exactly what you are saying. You are saying, among other things, that these 3 albums (I&W NOT included) are so wildly popular and loved amongst the fanbase that he shouldn't state his opinion that DT15 is better because the fanbase (which allegedly holds this consensus view) will be disappointed when DT15 can't meet the expectations he set. Your words are below if you need to be reminded.
"Let me explain it a little better: it is not about any one person's of their work; it is about knowing the favorites of the fanbase and keeping expectations realistic. To know the DT fan base is to know that (post-I&W) a record like Scenes from a Memory is wildly popular, and Awake and Six Degrees of Inner Turbulence are widely loved as well. So, again, saying, "It may well be the best one since Images and Words," is setting a lot of fans up for disappointment if your opinion is not shared by them right away, and like it or not, expectations do often subconsciously affect how fans react to new music"
