:: I don't know of any translators for custom flavours of TeX and MathML. If they exist then there are very few: in the vast majority of cases, choosing the application from MathType's compatibility menu just switches between copying raw TeX, MathML, or TeX wrapped in an HTML  tag. Maybe there are other cases like the Wikipedia one mentioned in the article: the output is just TeX as usual, but wrapped in a wiki  tag. This is hardly a custom translator and definitely not a "microformat". The text that I removed recently misrepresents this. (BTW, if you wrote it, what is EGO?) 

 :: The fact that MathType has presets to choose the right import/export format is still nice and worth mentioning, so long as it's honest what it is. It's currently mentioned at the end of the end of the section on application support, but maybe it could be made a bit more prominent. However, it would be nice to keep the current structure of one paragraph each for Windows desktop, Mac desktop and web applications; or at least have a well thought out replacement structure, rather than just plonking this fact at the start or end of the section. 

 :: A big problem with all this is that there's no reliable source for any of this. Design Science's website just claims compatibility with 600+ applications, without breaking down which ones have genuine embedding support (like OLE and iWork '09), which ones have special translators of some sort, and which are just generic copy/paste TeX and TeX  tags. Their works with page has products in all categories. Indeed the majority are just websites that allow image tags, and saying that MathType is compatible with these is a long stretch. It even includes applications where the only option is to export an image from MathType and import it into the application (e.g. Flash InDesign OpenOffice for Mac). No one outside the Design Science marketing department would call these applications "compatible"!
