About Wii U:

Price drop:
The reason they aren't lowering the price is because they have only recently begun selling it with a profit. After 3 years of losses, how could they rush going into red again.
The profit might be small, but at least it's happening. And with the line-up next year, they won't need one.
Not that it won't happen, but i wouldn't expect one before Zelda comes out next year.

Redesign:
Of all 3, Nintendo is actually the one who needs it the most. Changing the look to something that doesn't make it look like a rounded Wii is a must. Changing the name is also needed.
Almost everything about the Wii U needs to change.

Bail out:
Nintendo already said they won't release a new console before they please Wii U fans.
Changing to x86 architecture will do nothing for them. Actually, having the easiest and also powerful architecture never made them the winner.
3rd parties aren't supporting Wii U because of the architecture - because they never cared -, it's the low install base and lack of a market for their games, that's keeping them away from Wii U.
As i said in another thread, the most likely scenario is that in late 2016 they will introduce a new console seeing as the biggest Nintendo franchises will be already out and to take advantage of whatever momentum Wii U will have by then.

I only read the Nintendo part and it's pretty fair. Sony need not do anything, you may as well have put N/A for them.

None of the startegies will work on Nintendo.

except price cut, but having it too cheap would make some think ut's rubbish and the more talked about xbox/ps brand is better.

lol true... but that won't have been fair. Most of what i put for sony is basically in reaction to whatver MS may do. Sony will probably just keep releasing new colored consoles and bigger HDDs for a while. They wouldn't even bundle games cause they addthe games they would have bundled to PS+ instant game collectiong. Most they may do is offer a free 3 month PS+ trial.

Pretty much all this.

Whatever Nintendo does will be heavily criticised, but what you said about them riding out the storm is probably the best thing to do. Sales wise they have lost this gen but slowly and steadily building consumer faith with games and support will allow their next console to start off much stronger.

At this stage Sony can do no wrong, but I feel their momentum will drop if they dont seriously start supporting their console with more than 3 1st party games a year (sure Uncharted 4 will sell, and Bloodborne is hyped but I dont think it will sell that great, and Order 1886 might sell decently but is a delayed game, apart from that what else does Sony really have planned to wow their customers?).

MS are working on the rebound. They dropped the mandatory Kinect and are focussing more on games now rather than TV and sports like they did initially. A cheaper redesign would definitely help.
