Patience aside, I'm considering just going with the C1 myself at this point. Not sure how keen I am on G series wall-mounting. The wall has studs and it's pretty safe for a wall mount, but I've never done that with a TV and I might constantly be worried about it falling or something. Maybe more importantly than that, it might kill my security deposit next time I move around. I don't like how G1's art gallery stand looks either. The stand for GX is a lot better / more traditional. I could go with GX + a stand for like $150 less than the C1, so that's also an option. Not sure how they compare to each other, would need to really get into their specs.
Too bad I can't see into the future. If the G1's wall-mount is stable and doesn't do any real damage to the wall, then we're fine. Would prefer to get a G1, just concerned about the wall-mounting.
