The iPod nano 4G is coming, that’s for sure, but just how small will it be? iLounge has exclusive dimensional drawings (or at least, that’s what it looks like) of both the iPod nano 4G and the iPod touch 2G. Both models apparently share somewhat similar measurements as their respective predecessors, but will feature new shapes and features as a form of innovation that only Apple can bring. The iPod nano 4G is tipped to be the slimmest and narrowest iPod nano yet if the 90mm x 40mm x 6.5mm figures are to be believed. As for the iPod touch 2G, this comes in a more tapered enclosure and measures 111mm x 61.8mm x 8.4mm. These are just rumors and have not yet been confirmed, so make sure that salt shaker is nearby.
