Everyone has an opinion. I respect yours.
Mine is that if there is a firm fact in the past VG industry is exactly Sony's strenght in third party relationships.
Note: past, not actual related to Vita (that's exactly what I was saying: up to now there is no concrete evidence of possible relaunch for Vita especially because of the absolut lack of firm announcments)
Probably you're from 2004 or something.
Sony's relationship with third parties got worse and worse as time was passing; they basically lost 90% of their exclusives in this generation (many multi-platform titles but also many exclusives to other platforms, such as Dragon Quest, some Square Enix RPGs, etc.), and they already lost the only IP that could guarantee some kind of success to Vita in Japan. What you're saying it's not a fact, it's a legend based on the legacy Sony got after the PS1 era, where they really worked to have third parties.
