the strange things is though, that petrovich dies in mg2, but he's alive in snatcher. Then again, when did a Konami character really die? 
Yeah, Meryll dies in MGS (since Otacon is alive in MGS 2, 3 and 4 and you have to choose...) but later appears in Policenauts.
Snake looks quite -old- in the trailer. And Raiden is seen on the site with (Olga's) baby. Maybe in MGS4 snake dies and has to infiltrate heaven to get back his unborn baby from an evil priest...
@ Samor: In the cannonical story line, you'll resist Ocelots torture and thus saving Meryll; At the end of that version Otacon also survives. Since Meryll returns that is the true way the story will go on.
@Akuma
ROTFLMAO
And about Meryll surviving... Meryll did survive; Iirc something is mentioned about it in MGS2
Snatcher en Metal Gear franchises have several crossovers. But there are many discrepancies as well (even within the franchises).
For instance:
- In snatcher (msx and probably more japanese versions) Catreena is 14 years old. But on Sega CD she's an adult. Probably because of the shower scene, her being under age and the sexual inuendo.
- Snatcher (msx), Sd Snatcher and Snatcher (PSX) have different endings
- SD Snatcher's different side quests/ events.
- Metal Gear Ghost babel is in a alternate universe (some cross overs from MGS1 and some differences)
- etc etc
Look up some old posts on the now defunct metalgear.net. They discussed the issue at great lengths back then... Though searching might be hard since they moved around some time ago...
