That's funny and I'm with you on the audio upgrade hopes. Personally, I hope for hardware that can go fully toe-to-toe with Blu Ray standards- both video & audio (but I bet we won't quite get that).
I find all of these

TV threads hilarious compared to all other Apple product threads. Only in these, do you get people arguing against hardware progress. In Mac threads, people are never arguing against the latest graphics card or the latest processors. In fact, it's often just the opposite: rants against Apple for NOT building in the latest & greatest hardware... even if some of the latest & greatest may not be usable in almost any software available at the time.
Even simultaneously with this thread, you got all these people gushing about a retina display in an iPad, wanting an A6 instead of an A5X, wanting LTE instead of 3G, wanting more ram instead of the same- even though every single app in the app store works with the iPad 2's existing hardware specs and there really is NOTHING currently available that takes advantage of the cutting edge of an A6 or A5X, more ram or retina.
All our computers do everything we use them for today so perhaps Apple should not advance the hardware in new computers? Our iPhones work today for our needs so perhaps Apple should not advance the hardware in iPhones? Etc. You don't see much of that. Just lots of whining or enthusiasm revolving around advancing the hardware... wanting the future now.
But, when it comes to

TV, there are so many people that argue that 720p is good enough, global bandwidth must be in place before it makes any sense, "the chart", file sizes too large, and my personal favorites:
- "I can't see the difference so you can't either" (and all its variants) and
- "99% can't see the difference" as if they've surveyed the world when, probably 99% of the time, THEY (alone) represent their survey pool.
The funniest part of all is this: for those that feel SD or 720p is "good enough" for them, better hardware will simply play their 720p or SD to its fullest quality.
They lose nothing in their own experience if they get some hardware capable of a bit more than their needs (just like a new iPhone, iPad or Mac). Yet, every

TV thread that mentions 1080p is always full of these people who argue against better hardware- in this one thing- in spite of the fact that it will have NO IMPACT on them whatsoever.
I used to think this was just the usual "whatever Apple thinks" cheerleading, meaning that if Apple has demonstrated that they think 720p is good enough, then it is indeed good enough for all. But last year, Apple demonstrated that even they were moving on when they put a 1080p camera in the iPhone 4s. If Apple still thought 720p is good enough, that camera would be a 720p camera in support of many of the very same reasons people sling in arguing against 1080p for

TV. But even Apple moving on to 1080p didn't do it.
So I guess these people think that Apple is wrong about embracing 1080p too.
