It is also worth noting that TALENs were implemented for genome editing [0] before CRISPR/Cas9 [1]. And that there are ongoing trials in human subjects that use TALENs for editing instead of Cas9 [2].
Though I agree with a sibling comment that we might not find another system with the same advantages as CRISPR/Cas9 (ie, only having to generate RNAs to engineer site specificity, rather than the more intensive task of generating a protein coding sequence like you do with TALENs).
