Ah, but
Beorn, how do you know he
isn't a
Maia??

I have re-evaluated
Tom's position in the fates of
Arda, and I have come to the conclusion that although it may seem too scientific for
Tolkien's world, all
creatures and things are categorized. Whether an Ainu, a Man, an
Elf, a
Hobbit, a fish, or whatever; everything falls into some category. In some cases, like
Tom Bombadil or the steeds of the
Nazgûl in the LotR, this categorization is not as easy as it would seem, because the background and history of the character is insufficient, and therefore left up to the readre to evaluate.
But I personally now believe that Tom might have been one of the original
Ainur to have been created by
Ilúvatar; and I also think that, although it is not stated in
the Silmarillion as such, that Tom descended upon Arda some time before the
Valar themselves, which is why he could not be counted as one. The way I see it is that he is a secret agent sent by
Eru himself to ensure that things are in control in the Little Kingdom.
So, to conclude my little hypothesis and to actually answer the question of this thread, I'd say that as Tom is the unofficial Guardian of Arda, he will not leave at all.
PS: by the way MorgulKing, welcome to the forum! And the actual terms are
Maia for singular and
Maiar for plural.
