Seeing as you asked nicely:
There's a couple things missing from there (like Resident Evil Revelations 2), were on there but not mentioned for Vita despite being announced (Guns Up!), devs have mentioned potential Vita versions (Skulls of the Shogun, maybe?), have been announced since (The Swindle), or have already released on Vita and are coming to other platforms in that list (King Oddball). But yeah, tons to come.
Thanks! RER2 for Vita is included in their list as TBA (I think they mentioned it was coming this summer). I did the same comparing the lists of both Spanish and US blogs. Saw some games only appear in the American version. See them listed as US only (may be announced later for Europe, obviously):

TOTAL
List mentions 122 announced games coming for Vita in 2015
[*]36 of these games are mentioned for Vita only
[*]85 of these games are mentioned also for other PS platforms
[*]1 of these games is mentioned for iOS, Android too
[*]8 games mentioned for Vita appear only in the US version of the list
Now I have some questions:
- How many of these games will debut in Vita only?
- How many of these games are PS console exclusives (can be released in PC before, at the same time or after that, not announced for other consoles)?
- How many of these games are PS 'console debut'/'first on' (can be released in PC before, at the same time or after that. Seems pretty clear that will appear in other consoles)?
- How many of them are portable exclusives (not released, not announced for 3DS,iOS,Android)?
- How many of these games are multiplatform releases (debut at the same time on Vita and other consoles including non-PS ones)? *
- How many of these games are direct ports (only counts COMPLETE versions released in other platforms BEFORE Vita release)?**
- How many of these games are remastered versions/remakes/updates/enhaced ports (PSVita adds new features, new content, revamped visuals or other similar new stuff)?
* = At the same time I mean the same week or so, a few days away would count. I mean, not released months or years before
** = Complete means no demo, alpha versions, beta versions, early access, backer exclusive versions and similar unfinished non-commercial releases.
