No, the Forum content is transferred over to Discussions in HTML form. So it'll look the same, templates will appear as they were, but the wikitext markup won't be saved. You won't see the difference, but it would be impossible to later tranlate the posts back into wikitext.

@FizzFire: Edits on regular MediaWiki pages are not affected by the Forum retirement.
