I've had bad luck (or lack of foresight) with receivers; I end up buying ones that work for my present purposes but are rendered obsolete quicker than I would like. My first was a Pioneer Elite VSX-74TXVi, which couldn't support 1080p - so when I upgraded my projector to 1080p, had to buy a new receiver. My next (and current) was a Denon 4310, which doesn't support 3D - so when I eventually upgrade to 3D, probably later this year, I'll need another new receiver. Are there any big features like those coming in the next few years that I should have on my radar? If I buy, say, a Yamaha RX-A3020, am I going to be set for the foreseeable future (it says it even supports 4K, which is the only potential next big thing I'm aware of)? Thanks!
