I totally agree with you. But my TV is now a month old. And I got this Marantz NR1609 AV reciever very recently. The reciever is unused in box since I have not purchased the speakers yet. Yet everything is in plans and process now. So no harm in getting the new model Marantz NR1710.Every year new technology is getting released with hype and so the new models are coming up.
Assume that no new technology is getting released for some time may be for 2-3 years down the line ,then no market gimmics/ hype for new products and then no visibility to sell the new product.
I would suggest if you feel lame without the new technology, then u think about upgrading .I see you recently u bought this AVR ,be happy with what you have right now. If not ,you will not be in a postion to enjoy the current setup and finding faults/wrong in it.
Just my 2 cents.
"Happy listening" with your current setup.
PS: you may not be knowing how the eARC performs in your TV initial days .During initial phase each and every technology is half cooked one when coming to market( some thing like beta).you will hear lot of surprise with reviews.No offence on LG or Marantz here.i do own LG and Marantz product.
It's not that late...I Ican get this one in exchange with the new one.
Only thing I will have to wait till December till this is available here. It's ok with me.
I have made up my mind to enjoy it not less than 5 yrs till I think of upgrade it to the next level.
