The G2/G2+ does have improvements - I just don't know to what extent (compared to the changes they made with the 750/850/900/1000). I know it has the corner bracing now.I spoke yesterday (as of the time of writing) with a man who also owns a redsea. His aquarium (seam) is also starting to let go from the front. For some odd reason he's not alarmed by it, and is actually willing to buy the G2.
