One strong impression from the Pali suttas (due to the lack of discussion with Brahmins on the subject in the suttas) and the little I have read of the Vedas is the Vedas did not contain any systematic teachings on the subject of reincarnation.
The impression (from the little i have read) is the Vedas taught about two worlds, namely, this world & the other world, which i imagine was the heaven of Brahma. Otherwise, three worlds, here.
For example, I recall recently reading (somewhere) Sariputta & Moggallana were formerly disciples in a sect that believed in going to heaven with Brahma after death.
My vague recollection from chatsite banter, including by the Ven. Sujato himself, is systematic doctrines of reincarnation began forming in the later Upanishads; which 'reincarnation' aficionados, such as Sujato, who appear to go for refuge in non-Buddhist scholars, attempt to date prior to the Buddha; even though there is no account of any Upanishads in the suttas.
My recollection is the Ven. Yuttadhammo has posted on these matters, here and here.
