There may have only been 2.5 years between MM and OoT, but they were built on the same game engine. This one will likely be entirely from scratch.And 2009 is a long development cycle for Zelda Wii, especially considering that the game has already been in development for over a year.
Actually, if this is true I'd bet they use the same engine with some upgrades (i.e., Make it Wii only and take advantage of the increased CPU, GPU, RAM, etc.).
That's a way better use of their time than starting over from scratch...they'd never be able to do a completely new game AND make a new engine in 2.5 years, but if they continued using the same tools, they could do it.
PS: The original comment you referenced said there were 2 years between Majora's Mask and Wind Waker (not OoT and MM). Since WW was on a new platform, they were probably using a new engine (where as OoT and MM were probably using the same engine).
I suspect that WW and TP were using the same basic engine (since TP was originally intended to be a GC game), but with a different rendering pipeline (using complex textures instead of cell-shaded colors). But, since it was both a Wii and GC game, the engine itself (and the tools) were almost certainly the same. The content was the same as well (which is why TP looks like an awesome GC game, but not so great as a Wii game...which will become more apparent as more real Wii games are release
