if they don't want to port anything or work on a platform they simply outright wont. Dead Space: Extraction is a good example of this.
Dead Space: Extraction is a wonderful example. Thanks for bringing it up. Let's review Dead Space: Extraction's timeline.
* EA stock was falling. Wii was shooting the lights out. Investors were not too happy.
* EA announces they "bet on the wrong horse." Would be "shifting focus to Wii." As evidence of this, they announce that
Dead Space is coming to Wii.
There was much excitement surrounding this RE4-like game coming to Wii. Until ...
* EA announces that Dead Space is an on-rails shooter prequel, and the real Dead Space isn't coming to Wii, at all.
They made Dead Space: Extraction
in order to say to investors, "Hey, we tried. Wii just doesn't work for our types of games." If their stock was good, then, yeah, they probably wouldn't have even bothered with that. They made Dead Space: Extraction in order to keep the hounds (investors) at bay by giving them a bone (empty promise of Wii support).
To quote from a thread linked through my tag,
EA Shift Focus to Wii
Shifting to Wii , RIP February 2009 - March 2009
he was a good and friendly shift
EA is not interested in giving "real" support to Wii U, currently. I'd imagine this is because they have horrible expectations for Wii U's ability to sell core games. If the real sales say otherwise, they may change their tune, but at this point, you shouldn't really trust anything coming from EA when it comes to Wii U.
Has Nintendo stated that you can install games onto an external HDD? If this is USB 2.0, isn't that going to have serious loading problems?
Games bought digitally can be stored on an external HDD. Blu-Ray read speed on the drive is 25 MB/s, so as long the HDD gives the same throughput, there won't be any extra delay compared to playing the game off the disk.
