just because you dont think it needs a whole article doesn't mean the rest of the gaming community agrees with you, info about Duke Nukem just started surfacing this year and while its out there i would not put it past GI to run a big reveal on the game and really bust it wide open. now i think this is a case of us as ES fans seeing evidence that looks substantial to us but in reality is rather trivial, seriously its a direct title reference dont be so blind as to ignore contradicting evidence.
This was discussed a couple of threads ago. To just repeat the results: yes, you're right that it's plausible that the Feb GI cover will be DNF. However, the "4ever" is not definitive - there are lots of equally plausible explanations for that word choice which don't imply that the cover will be DNF. So that tweet, by itself, does not rule out the Feb GI cover being TES V.
What people are claiming should increase our confidence in the Feb GI cover being TES V is (1) Pete's tweets that Bethesda had fixed an announcement date for their next big project (presumably TES V), and that the state of TES series would "become clear before too long" (I'm not sure if that's quite right, I'm quoting from memory); (2) this latest piece in the Jan GI, which seems like it's, as it were, warming people up for a new TES title. These two bits of evidence point not only to there being a new TES title in development, but, more specifically, that title being announced
soon. In contrast, while of course we know that DNF is in development, I'm not aware of any evidence which suggests that very soon there will be a massive release of new information about that game (of course, this may just be because I don't care about DNF).
Let me put it this way. You might think that, as far as the chances go for being the Feb GI cover, DNF and TES V are on a par, because both are games about which people have been craving information. The point of the two bits of information I just mentioned is that they are a tie-breaker - they show that DNF and TES V are not a par. TES V has a greater chance because we have evidence that
in the near future we'll get information about it.
(Actually, I think a stronger point can be made. Even if you think that,
just in light of McNamara's tweet and the "4ever", DNF is a more likely Feb GI cover than TES V, it still seems reasonable to think that
all things considered - ie. taking into consideration the other bits of evidence I mentioned - TES V is the more likely Feb GI cover).
