I consider new game announcements considerably more important than localizations of games that are supposedly not very good. Vita Game Heaven had interviews, some nice game trailers, dlc announcements, and date confirmations for several titles. As well as the announcement of 6 new Vita games. Admittedly, half of that six are logo announcements, but still. I'll give you presentation though, Vita Game Heaven was an absolute mess and felt like SCEJ was just advertising their Youtube channel.
Outside of GAF and other hardcore forums the response to Game Heaven did seem to be a bit better. I suppose it helps that news outlets generally tried to cover all of the announcements rather than duckroll's "PSO2 announced, MGSHD + Persona 4: The Golden dated nothing else" approach and didn't have a forum thread hyping things up days in advance with speculation. For example, I don't think there was ever a thread of GAF about Inafune's Vita game, which admittedly was announced with such classic quotes as "It will be a very Inafune game", but at the same time it sounded like SCE is the publisher, so I expect that to exist. The non-coverage was weird since Duckroll was one of the people who tried to keep VGH expectations in check. He seemed to realize that if Sony had any big games that they weren't going to announce them without an actual press conference.
SCEJ probably shouldn't have done the whole teaser site to get people hyped, and they could've used a better name (Vita Game Heaven does imply it would entail announcements to save Vita) but I still think the raw announcements were better than Nintendo Direct even if it was really poorly told. I'll admit The Last Story announcement was good, not because I was waiting for the game, but rather that it showed that Nintendo was gaining some sanity in regards to allowing games their western branches don't want to be localized by third parties. That said, it sounds like TLS may be a very special case.
