Trust Planet not to do this without good reasoning. There will be substantial differences between the two, and people will still snag both of the shelves quickly. With this, Planet effectively corners the mid end market (Etek3 LT & AM, Geo [as a price drop is expected for base Geos], and the Geo+) as well as keeping strong contenders in the high end market as well.
I'll be picking up a Geo2 for sure, and possibly a Geo+ for good measure.
