If we were talking about a 1GB update on a PC or console, it's never too much of a problem, especially considering that most consoles have at least 120GB of internal memory.
When we're talking about a PSV update for Killzone: Mercenary
though, it's a completely different story. PSV memory cards have much less memory than consoles and PCs - and when a title has a day-one update of 1.1GB, and a second 1GB update the month after, it's going to cause some problems.
Admittedly, the first update will be deleted from your memory card, but only after the second one has installed.
According to Matt Porter, the technical director at Guerrilla Cambridge “We are currently investigating solutions to reduce the overall size of the title and free up more of your valuable memory card space. We hope to be able to share more news on that work very soon”.
You can find the rest of the details, again courtesy of Porter, below:
"The other main area of work has been to provide a better distribution of respawn points across all game modes. The intention here is to give a better balance to the multiplayer games. We’ve also addressed the issue that some of you were reporting with load-out slots not being unlocked, in addition to problems with the melee medal (which was always being awarded as a “bronze”). Finally, there are also a number of stability fixes, to address some of the crashes that have been reported."
