I'd be very surprised if the production version's any different than that. Screw ports in a vehicle are every bit a part of the sculpt, and whether the Toy Fair one with the attrocious screwholes is a hardcopy or not it still is 99% likely those holes will be there.
The question is how they can be covered up now more than anything... Hasbro hasn't glued a ship together yet though, that I can think of anyway, so I'd not hold much hope for that. The mold toolings would have to be completely different for that to happen and those holes not to be there.
Plugs would be nice, but not Hasbro's style I'm thinking.
As far as my issues with scale, the right side wing cannon extends BEYOND the nose of the ship. That's just wrong... This thing's all over the place with scale as much as the POTF2 X-Wing is. I don't believe there's any reason this should run $80+ in cost, especially considering the sheer # of these Hasbro is going to inevitably sell with it being a general release item and not an exclusive (not to mention potential future repaints/reissues of it).
Like I've always said, if I can get a perfect 1:18 scale P-38 Lightning Interceptor, I should be able to get STar Wars fighters to-scale too... This one I'm not 100% sure on that motto I have, since the ARC's actual dimensions are a bit of a mystery yet, but it looks like it's smaller than the FX X-Wing at this point, which is just wrong for a 3-seater fighter.
Hell, it's as big as the Jedi Fighters which are smaller than it in the movie... That looks odd to me.
To me, Hasbro can do better and I think they'd see a better reaction on vehicles in general if they tried a little harder. Kids attention spans don't stick long enough to a toyline that the vehicles matter anymore I think... At least not with Star Wars it seems. Of course this could be a surprise hit... The Gunship wasn't though, and that (even underscaled) I thought of as a REALLY nice toy for even the $40 pricetag. This I have a lot lesser opinion of myself.
We'll see though. Those screwholes seem so blatantly noticeable that you'd think a sticker sheet may cover them, or plugs... I dunno. Stickers would be the most hopeful thing anyone could want right now, like Deanpaul mentioned I believe.
If not, maybe someone will make a printable sheet people could just print up that matches the colors around each screwhole. It'd appease the people who don't like the way it looks anyway and that's a pretty big step incase Hasbro just leaves it that way.
