As of yet there is no confirmation if any of the rumors are true. You are correct, the fact that the website has not been updated since the fire means it's hard to know just what, if anything, is happening at KTM.

If you type "kells transport museum" into flickr.com you'll see the state that most of the buses have deteriorated to. 190jzl is correct, almost all of the rare machines have reached an advanced stage of decay and are as good as scrap by now, and I know it's a terrible thing for me to say as an enthusiast, but I don't think it much matters at this stage if the Revenue seizes the entire yard and sells what is left of the buses to a scrap merchant.
