The current plan is to do our best to render the same output as before. So if you were showing off how to bold something in wikitext, for example, by adding:

This is how you bold.

Our goal is to render that as:

This is how you bold.

If for some reason we can't, like if there's something too complex for conversion, we can fallback to something like rendering it as pre-formatted text. Our hope is that that is rare.
