Because most third parties are unprofessional, either getting paid to skip nintendo platforms or skipping then out of stupidity.
Anyone saying that wii u can't handle the games or that they don't sell is just another stupid hater.
The wii u proved more than once how far from ps360 it is in specs capabilities, putting it in the same range as ps4/x1, but with less raw power.
The games sell, plenty of titles are getting 300-500k+ sales, and no amount of cherrypicking will change that. the big multiplatforms that idiots keep mentioning as having low sales(AC, COD, batman) were released when the installed base was like 3x smaller than it is now/will be in the next few months and those games STILL SOLD DECENTLY. 200-300k is surely enough to make a profit and with the bigger current installed base they would easily get 500k+.
