At launch I paid full price for the Special Edition of GTA IV, and will probably never do it again.
I'd consider it for BULLY 2, but I've heard from someone close to the studio that the original dev team bolted to do a 4X space game after wrapping that gem. If they're not handling the sequel, I've got limited confidence in the sequel. It'll be day 1 for me, but an extra US$20~30 for some trinkets which set the publisher back an extra 5 bucks isiffy.
If there was a Special Edition Classics version of GTA III, I'd pay ridiculous sums of money for something with a poster, soundtrack CD, poster or wall scroll. Maybe a scratch-n-sniff book of all the principal characters, and hugging pillow of Donald Love. Well, "ridiculous sums of money" compared to what the game can be found for used or even Platinum/Greatest price-wise... say US$80.
