The templates were compared to the "spoiler" templates. Not to drag all that up again, but I found the comparison interesting. The same basic point seemed to be made there, though, that such templates patronised our readers, who can be expected to realise that the article they are reading is about a future event (and if they can't, then that is more likely to be due to bad writing in the article, than the reader's comprehension skills).
My personal current favourite is at:
http://en.wikipedia.org/wiki/Proposed_Constellation_missions
"This article or section documents a scheduled or expected spaceflight." (...) "As of early 2009, crewed flights for NASA Project Constellation missions are planned to begin in around 2014."
On a related note, the spaceflight articles have some of the more interesting variants on the "current events"/"future" templates I've seen. In addition to the above, at the time of writing, we have:
"This article contains information regarding a space mission that is scheduled to launch in the next 2 days."
http://en.wikipedia.org/wiki/STS-128
"This article contains information regarding a launch site that is scheduled to launch in the next 2 days."
http://en.wikipedia.org/wiki/Kennedy_Space_Center_Launch_Complex_39
and my personal favourite:
"This article contains information regarding a rocket that has recently been involved in a launch failure."
