Posted on behalf of N. Ganeshan:

I would like to draw attention to this paper on Munda expansion from South East Asia.  
Munda people expansion is said to be only from 3500 BP.

I hesitate to pass this popular-science treatment of the question along, since it is tinged with
some personal animosity, but this just appeared two days ago:

    There is no consensus about which language or languages the
    Harappan (Indus Valley Civilization) people spoke.
    The script is considered by most to be logo-syllabic, not
    heiroglyphic.
    Farmer, Witzel, Sproat consider it to be a sign system rather than a
    script associated with any particular language.

    To All, While going through some books on Indus valley civilisation
    , I failed to find out one answer. Though the Harappana & Mohenjo
    daro script has been inferred as more of a Hieroglyphic type, what
    dialect/language did they speak ? Would love to be enlightened on
    this point. ALAKEND DAS.
