What about
- HDD < Could we see 500 GB? Damn I still think it would be little. I have several 100 Gigs of Music alone, I would like to have from my Itunes on my 360.
If the adapter could be opened, and a 2,5'' HDD could be inserted, then it would be like PS3. Infinity upgradeable.
- Size/Weight/Heat/Noise < Sony always has the advantage because they are a hardware company. Microsoft is not. But if they could reduce, the Size and weight, and make it run cooler and less noisy. It would be amazing. PSTwo was 50% smaller than the old PS2. I still use it because it's such a small and beautiful DVD player. It looks really cool.
A Small 360 Would also be a cool media center device. If the weight was reduced as well, and Hard Drive upgraded, maybe people would have their movies and music librarys chugged along with it.
- Colors < It's been 4 years. It's a about damn time they got some new ways of letting people customize. We saw the new 360 Box Art. Was not that different. Maybe something like Gun Metal, Silver, Carbon Fibre, Matte Black, Piano rubber black. Lol, it would be cool if they could make a beautiful grey design. Grey electronics is so 80s and 90s crappy desktop computers. Everything is so Apple now-adays, including the regular 360 in design. A radical departure would be cool.
- SKU < Everyone said that Arcade SKU was for retards, but in retrospect it was a smart enough move by Microsoft. It sold well in some regions. I even know a few hardcore gamers who had no interest in online, so they sticked to a Arcade.
I think again they should have 2-3 SKU's. One Low, with a 40GB Harddrive, and a few accessories bundled, something along the lines of a Elite with a 120 GB and some good stuff bundled.
And then they should have a high end 400 USD SKU, with 500 GB HDD, Blu-Ray, Wi-Fi, Extra Controllers, faceplate, few oldie games(bundle it with Table Tennis/Halo 3/Mass Effect or something?)
