Pls compare both TV before you change decision.
If you like 3D that you must be carefully because of HX850 should be better than Sharp.
Have you tried to call the shop and cfm the actual date of delivery instead of waiting.
I already received TV last week since I had pushed AV Life for delivery...........
3D is good effect for HD and feel comfortable. It seems better detail than 2D when play BDP.
I am user and hope can help you so..
If still you can wait...........pls better wait more week and trying to pushing your shop for delivery.
Thanks a lot as waiting over 6 weeks and they said the delivery date may be end of June and I found I can save the money and waiting time. That's why I have this thought.
