1. Disc Drives
As someone who loves buying games digitally on both Wii U and Steam, I welcome the death of disc drives. I know there are a lot of people who are going to resist this idea, which is probably why it hasn't happend with the Xbone and PS4, but it's inevitable.
Not having to put one in future consoles would free up internal space for smaller, cooler designs. This would also make them cheaper to manufacture and, hopefully, buy... if perhaps only slightly.
2. Multiple Skus
Multiple Skus are designed to offer people a choice between the premium model with all the bells and whistles, or the slightly stripped down version at a more attractive price point. What ends up happening is confusion among the populace who's not as "tech educated" as your average hardcore gamer and lack of support for premium features.
For instance, it's hard to have really good support a built in hard drive if only some of the consoles have them.
I hope this generation of consoles is the last one we see with multiple hardware Skus. Really, the only console of this coming generation with multiple Skus is the Wii U, or was. With the recent price cut, the "basic set" seems to be a thing of the past. With no sign of different versions of the PS4 or Xbone, this goal might actually be in sight.
3. A lack of built-in storage
Nintendo has been mostly guilty of this one lately. The Wii U "deluxe set" has 32GB of flash memory, while the "basic set" has only 8GB. Either of these works well for simply saving games and downloading a few virtual console or other little eShop exclusive games, but if you're downloading full retail titles then that much space won't last very long.
Maybe getting rid of those disc drives would leave plenty of room for a full sized HDD... whaddya say Nintendo? How does that sound?
4. Scarcity at launch
I have a feeling that the days of having to wait in a long line on launch day or checking specialty console tracking websites to see if a store near you has a Wii are over. But just in case, I'm going to throw this suggestion out there. Let's make sure that when a console is launched, there are MORE than enough so everyone that wants one, can find one.
I suspect that PS4 and Xbone (especially Xbone) will be available for everyone when they launch, let's hope I'm right about that.
5. Super high prices
When the PS3 launched with the "cheap" version being $499 and the premium model coming in at $599, people weren't exactly thrilled. The Xbone and it's $499 price isn't inspiring much delight, especially with the PS4 launching at $399 and the Wii U now $299.
One of the (very few) advantages of console gaming over PC gaming is the inexpensive hardware. If I'm going to spend $600+ I might as well just build a decent computer and play games on that.
That was my list, but what do you think? Anything to add? Disagree? Leave a comment.
