People who don't believe Marth will be in Brawl:
Pellham says he's out
Enduin wouldn't be surprised, but eh, that doesn't count really (retracted!)
jj984jj said there was a fair chance he'd be out for Ike; not sure if that counts either (retracted later!)
Somnid goes for the gusto and says Ike is in and Marth is out, but in fairness he later says he'll stay
if the characters are different enough
MrCheez says Marth's probably gone (retracted later!)
papercut (who?
) is sure Marth's out
Will edit in more as I find them.
Edit 1:
VegaShinra calls it safe to assume Ike's in and Marth's not
---FROM THIS POINT ON WE KNEW ABOUT IKE---
Proven thinks Marth's likely out
Dark Ninja seems to fear Marth's gone, though that might be sarcasm... in any case, he later decides that Marth is in due to the Falchion icon (retracted later!)
AMUSIX says Ike "might" be replacing Marth and Roy; not sure if that counts
Kevtones hopes Ike is proof that Marth is gone
PkunkFury can't see Ike and Marth being together since they look too similar
Android18a would be amazed if both Ike/Marth were in
EktorPR highly doubts Marth
Again, more coming later.
Edit 2:
Raging Spaniard shares the opinion of PkunkFury on similar looks
EricDiesel is 99% sure Marth's out
Shig figures that Marth (/Roy) was only in because there were no international FEs yet and now he's probably gone
CrushDance, I think, is kind of worried about Marth
playstencil thinks Ike is replacing Roy/Marth (at least that's how I read the post)
LegendofJoe is "fairly certain" Ike is an "updated Marth skin"
---AFTER THIS POINT WE'D SEEN SOME OF IKE'S MOVES---
Cosmonaut X says Marth is likely gone
Leondexter boldly says "It's obvious" Marth is gone
Haunted One is willing to bet on Marth being out (retracted later!)
...
Edit 3:
MrCheez goes back on earlier and says he thinks Marth will remain!
MasterMFauli thinks Marth is gone and
ban bets with Zeed about it
perfectchaos007 calls Ike a Marth replacement, though I'm not sure if he really means that or is just commenting on other lines of reasoning
---FROM HERE ON WE KNEW OF FIRE EMBLEM DS---
Dr. Hadji says Marth's out unless he's an alternate costume, and later
ban bets with Zeed about it
Dark Ninja has no fear anymore and calls Marth pretty much confirmed!
Haunted One retracts his opinion and says Marth is in!
Danthrax subscribes to the PkunkFury and Raging Spaniard school of thought
jj984jj considers the DS remake and now believes Marth is in!
lsslave is losing hope
Edit 4:
Enduin is now almost sure Marth will be back!
