Out of curiosity, why exactly do you think that being exclusive intrinsically increases the propensity of the software to impact hardware regardless of the actual sales potential of said particular titles?
As opposed to multiplatform titles or ports of titles from more established or proven sellers?
Because people who want those titles are unable to get them on other systems, necessitating a purchase of the system to buy them unlike Vita where a lot of the games were or had been available on other systems. For example, Vita jumped from 10K to 50K because Miku was available only on Vita when it launched, unless I am mistaken. If it had also been available for PS3 on the same day, I think that (in the situation last year) it would not have done nearly as well at pushing hardware.
I propose a similar thing could happen with these titles on Wii U on a (much) smaller scale, but rather than pushing Wii U's hardware up, might keep it from falling back down to 4K levels.
This is the reasoning I had for my statements based on pieatorium's statements and comparisons.
My original reasoning was that the Wii U hit its lowest points in the three months between Game & Wario/Dragon Quest X's release and Pikmin 3's. During that time there were only 5 games released*3 and no first party games (which made up 3/5 best sellers on the platform, iirc, at that time*) and only one exclusive.
Therefore, I expect a period of about three months which will see ~9 games (re-)released*2, the majority of which are exclusives or first party games (5/9), will not see a return to the lowest numbers seen in the 3 months prior to Pikmin 3.
Again, I'm willing to be proven wrong by actual numbers as we move forward. It's just my expectation.
