Question: What is the plural form of "status"?

Answer: 
In Latin, the nominative plural of *[status](https://en.wiktionary.org/wiki/status#Latin)* as a 4th declension noun is *statūs*. This would be uncomfortable in English, and so the English plural is *statuses*.

The Latin adjective has a different masculine nominative plural of *statī*, but then means something more like the English *static*.
I see that I've very late to answer. I usually try to avoid the use of "status" as a plural, instead option to use the near-synonym "**state**".

Take for example these three attempts at pluralizing "status", all of which I've seen coworkers using:

> 
> The product should support the following statuses: Red Green Blue  
> 
>  The product should support the following status: Red Green Blue  
> 
>  The product should support the following statii: Red Green Blue
> 
> 
> 

None of those sound natural, and one is objectively *wrong*. The issue is sidestepped by substituting "states":

> 
> The product should support the following states: Red Green Blue
> 
>
