I too would be thrilled like fireworks for an HD collection of at least SR through Defiance-hopefully with BO2 as well, which is still a very good game and just as fascinating to play through!
I pre-ordered the Ico & Shadow of the Colossus HD release, and the Silent Hill HD collection, and they are magnificient on a flatscreen tv!! (SH is awesome, but I'm upset about lack of original voice work in SH3. The new voices are god-awful, I don't know why they did that. Eidos and CD-be sure to keep the original LOK voices PLEASE! don't butcher our game!!)
LOK HD Collection would be the best thing to happen in a long time! Remember to check the list here in the forums on how to support the release of more LOK games. Buy them from the Playstation store, request them on Steam, buy them for PC in digital downloads, etc. And stay on the forums!

I do my best to get on these forums enough and continue showing an interest. I lead a very busy life, and sometimes don't return for months at a time, but I always come back. Eidos/ Crystal Dynamics if you ever release a new LOK game you know I'll be pre-ordering that baby!
