As much as I would LOVE to see TES 5 on the Mac, I'm not too bothered by it if it didn't have official support.
Oblivion and Morrowind run extremely well under cider so I don't need to boot Windows anymore to play them. It's even easier to play PC games now thanks to CrossOver Games and Parallels Desktop 6.
The Elder Scrolls games are so good that I wouldn't mind buying a new copy if they ever released TES 5 for the Mac at a later date... I say this because I know for sure that I'm getting a PC copy the DAY it comes out just like I did with Oblivion. I never regretted the purchase. Bethesda is awesome and I'd support them 100% of the way if they were to make it easier on my end. Granted, not everyone's willing to do that so I hope that Bethesda will be wise and not screw us Mac users if they ever decide to support us (like denying a Mac version 2-3 months before releasing one... like that Dragon Age fiasco that EA did). It isn't too far-fetched considering I've heard that they're working closely on a iPhone/iPod project.
One thing's for sure, any Mac version (if any) would be released as digital download... As much as I prefer a physical copy, I don't see that being that good of an investment on their part. I just hope there won't be any crazy DRM.
what about mods.... for some reason Mr.Jobs seems to have a vendetta for free content, apple has tried everything in its power to squash creative minds that don't go through the "proper" avenues..... just saying if freeware apps where an issue for him modding might be as well
Erm... I play plenty of games on the Mac that support mods. What Apple is doing is prevent developers to screw around with the system and make changes to BASIC stuff like menus and windows appearances/functionality. If it's a window, it needs to be draggable, you need to be able to minimize it and close it, etc. still like that. Some developers just want to create some "creative" UI just for the sake of it looking cool without ever thinking about the functionality behind it. Adobe is one of those companies who wants to be able to change the interface just the hell of doing some fancy crap we don't need.
For example, I'm on a PC right now and I'm looking at Fraps (just look for a screenshot on the web if you don't know how that looks like). It's a pretty basic app. Why can't it use the basic window? Why doesn't it use the standard window tabs? Why are all the buttons in red and blue and why aren't those buttons basic windows buttons? Why? No reason. They just wanted to do their own stuff. And I've seen some crazy "creative" stuff when it comes to software.
There's a ton of Mac apps that support plug-ins, even those that affect the system. So that's not an issue.
