Confirmation of Type-28

Is there actual confirmation that the Type-28 actually exist? From the Type-25's Trivia section, "the Spirit dropship was erroneously designated as the "Type-28 Troop Carrier" during the development of Halo: Reach; this was soon corrected following the release of the game. This error, however, persists in the 2011 edition of the Halo Encyclopedia.[5]" Even the latest source on the Spirit seems to indicate that the Type-28 is nothing more than a typo. — subtank 11:50, 23 January 2018 (EST)

The 2011 and 2010 version of the Encyclopedia shows the Halo Wars 1 variant. Not the Halo Reach/CEA variant. ;) Both the Type-25 and Type-28 have distinct designs and no source says they are both Type-25 Spirits. The Type-28 is also seen with a Gravity lift into the cockpit of the Spirit(Halo Wars 1) Something that isnt seen in use at all in the T-25 model.(if the Type-25 does have it, we just never seen it used)
Plus even if the Encyclopedia used the error to get the Type-28 classification(nothing to say it did or didnt mind you). Its the only source giving a name for this specific Spirit at all, which would of needed a page regardless, its a case of we use the only source we have and change it if needed, wont be the first time we used a term from the Encyclopedia, that 343i may later change. (Installation 04B was a term born from the Encyclopedia)--CIA391 (talk) 16:00, 23 January 2018 (EST)
I agree that it was most certainly an error. Halo: The Essential Visual Guide also specifies that it was the Type-25 in Halo Wars. Halo Waypoint also makes no mention of the Type-28, but mentions the T-25 and T-57. --NightHammer(talk)(contribs) 22:27, 23 January 2018 (EST)
The Visual guide for items that do have numerous variants sometimes just uses the name of the item spotlighted.*Edit I made a oopsie in my example lol*
And the Visual guide spotlights the Type-25 variant. Never showing the Halo Wars variant in it.
Aka my main arguement is, in both sources you two are showing the Halo Wars variant is never shown at all. So it does leave it open for us.-CIA391 (talk) 06:45, 24 January 2018 (EST)
