-The removal of any realistic transportation system
Started playing ES with Morrowind, didn't you? I'm trying very hard to recall, but unless I'm senile, Arena and Daggerfall didn't have "realistic" options either and you
had to use fast travel to get anywhere in a realistic amount of REAL time. The only other option was walking, and it could literally take you DAYS of real time to get there.
-The removal of Attributes
Speculation at best. Granted, the GI print article doesn't even say if they're in, but given it's a staple of the system, they probably are and they just didn't think about it when reporting on it.
-The removal SPELL MAKING? REALLY?
I've not been able to find a trustworthy source that says this is out. As much as I'd love to take these foreign sites at their word, they all seem to be engaged in wild speculation.
-Some sources say that we can't even talk to all NPC's. (although this could be mistranslation)
Probably mistranslation. There have always been NPCs with little or nothing to actually talk about, but even those still had random rumors. With Radiant Story in play though, who knows, random NPCs could be more important than we know.
Personally I'm not worried. I've seen enough to be convinced they're honoring the series properly. I'd suggest just being patient and waiting for Bethesda to put some official stuff on their own website once the GI coverage is over.
Transportation- Oblivion had horse and mage guild transportation
Actually Oblivion doesn't have Mage Guild transports either. Only horses.
