I don't know of good tools already existing, but if someone is interested in creating them... :)

I've not had great experiences with HTML-based presentation tools, though in theory they should be pretty cool.

Possibly the sanest thing is to do template presentations in LibreOffice/OpenOffice, save as .ODS, and either manually translate them or create a tool to extract text onto wiki pages which can then be run through the Translate extension, and used to regenerate another .ODS file. Or one might be able to work with .PPTX if you're brave. Anyway, both are zipped XML these days so it should be possible to create such tools.
