The discovery of longer texts — whether on durable media at unexcavated sites or as impressions on recovered sealings — would transform the field. Rakhigarhi and other major Harappan sites that remain incompletely excavated are potential sources.

Machine learning approaches that can model the combinatorial structure of the sign system, trained on corpora of known logo-syllabic scripts (Sumerian cuneiform, Egyptian hieroglyphs), may identify structural patterns not visible to manual analysis. However, the extremely small corpus size remains a fundamental limitation.

A bilingual or multi-script text — the "Rosetta Stone" of the Indus — would immediately transform the problem. The Indus Civilisation maintained trade contacts with Mesopotamia, and cylinder seals with Indus motifs have been found in Mesopotamian contexts. The possibility of a bilingual seal or tablet cannot be excluded.

Advances in ancient DNA studies may eventually resolve the linguistic affiliation of Harappan populations independently of script analysis, by connecting genomic ancestry with known language family distributions. The 2019 Rakhigarhi aDNA study (Shinde et al., ''Cell'') provided initial evidence, though the linguistic implications remain debated.

Refinement of the sign list through allograph analysis (Daggumati & Revesz 2021) and application of phylogenetic methods to sign evolution may clarify the script's typological classification, even short of full decipherment.
