NIB 65GT30 for $1999.00 Canadian or Wait for 50 series?

I have bought a new in box September build 65GT30 tv from a large Canadian retailer for $1999.00 plus taxes(delivery on Tuesday), but if it turns out to not have the green blob or pink hue, doesn't have the FBR issue or buzzing will I still regret not waiting for the 50 series? I have seen the new 50ST50 tv's but they don't look too different to my eyes although I am not an expert. I currently have the Pioneer 5080 and am looking for something bigger. I have been pouring over threads but nothing convincing enough either way. I have 15 days for full money back and 30 days for in store credit. Give it a try maybe?
