A 1609 would be from the middle of 2008, or 4.5 years old. That isn't exactly a new piece of equipment you've got there, especially since HDMI itself was really only a year and a half old at that point. You're frankly lucky that thing even switches HDMI.
I rolled a Yamaha RXV2500 up until February of this year. It was a higher end receiver, one step down from Yamaha's top-end-but-older RXZ9. It predated HDMI by about two years. When I replaced it, I didn't complain that I was getting "screwed" by newer gear. I recognized the issue as exactly what it was. I had gotten 7 years of good use out of the thing, but that RXV2500 just didn't support the features I wanted any more. Now there is a cheaper, tiny Marantz NR1602 in its place. It does Audessey MultEQ, and all the modern HDMI stuff you'd expect. In half-a-decade when it no longer does what I want, I won't be getting "screwed" then either.
So, BD and keyser, instead of spending $350 on a Wii U, maybe the correct upgrade would be to get a modern receiver with that same money? I mean, that's pretty obvious to everyone else here, right?
