I think it's just because their RPG is rumoured to finally be getting shown and we don't know a working title for it yet. I think GIFs and general fan craziness are what I enjoy most about E3. The actual shows never deliver on the hype, while usually good, people online just go crazy with unrealistic expectations and ideas that what is still a corporate and shareholder based conference can be full of "jokes/megatons and craziness". I mean Shu and Adam Boyes wanted to show that game sharing video last year on stage at E3 and Jack Tretton while endorsing the overall project said no to it being on stage. On that note going to miss Jack this year, it was both awkward and charming watching his nervous self each year and the little jokes he tries to make about Sony (pre-E3 leaks/pink PSP/etc). New guy has a lot to live up to, as I said it's a corporate show, but nothing is worse than a dead personality reading off a prompt.
Hahaha i was just teasing, totally got it and find it funny and uplifting as well. Especially this new usage of megatons heh heh. Hope Guerilla have a lot to share, i'm always up for more Killzone
They could also do the PS Vita touch-based cooking show spin off, Kalzone: Pepperoni Fall, that would sell like hot pies
