3rd parties deserve at least half of the blame for the poor 3rd party sales on Wii U. Except for Ubisoft (Rayman, ZombiiU) and Deus Ex HR (Wii U is best version), they have all done really shoddy jobs on their ports. If you use zero effort on porting over to another system and it has terrible FPS and bugs, you don't deserve sales.
Nintendo has proven if you fully utilize their GPU (which is much much faster than the 360/PS3) and not have CPU focused games (so you'd have to slightly alter games from X360/PS3 instead of straight porting) you can have great looking games at

That said, I am looking forward to Xenoblade and Bayonetta 2 - Wii U could really use some more gritty games but that's just not Nintendo's bag. It's got to come from their 2nd/3rd party partners like Platinum, Monolith, and Atlus.
I got my PS4 for Destiny and I enjoyed the Alpha so that can't come soon enough.
