1) I'd love a new Metroid game, but more on the sake of principle. Like the 2D ones more than the 3D ones, so with a Metroid Prime 4, I'd need to play the first trilogy (but I did play through Hunters, because I'm a masochist)
2) Similar, I'd need to play through Dead Space 2 and 3. Arguably this needs a sequel more, because with 'Metroid', storywise, there's little to do beyond 'Fusion', whereas Dead Space 3 ends on a cliffhanger.
3) No comment
4) Eh, don't particuarly see the need. I liked Rogue Squadron 1 & 2 (1 more than 2), but they're more games set in the Star Wars universe rather than carrying out a story of their own.
5) No comment
6) Never played the first, but liked the concept, so I'd be onboard with it. And hey, got Alan Wake 1 on Steam before it was taken down, so might as well play it one day.
7) Strongly doubt this will happen, like, ever. Doesn't help that I haven't played the previous TOR games, but I'd be behind this if it was released.
8) Short answer is "hell yes!" The longer answer is much longer, but, well, yes, I want Warcraft IV. :(
So, can't really disagree with anything on this list, but if I were to submit another eight, and confining it to unannounced sequels, I'd go:
1) Advance Wars 5 (come on, Fire Emblem got a revival, but Advance Wars hasn't got a new installment since Days of Ruin in 2008).
2) Command & Conquer (okay, it doesn't have to be a sequel, just a return to the series, but if we're playing the sequels game, make it something like Red Alert 4. Generals 2 was canceled, Tiberian Twilight was lacklustre, so maybe Red Alert is the way to go?)
3) Golden Sun 4 (come on, you revive an excellent duology for a third game that ends on a cliffhanger? Come on!)
4) Half-Life 3 (yeah yeah, I can dream. Heck, I'm not even that fond of Half-Life, but I'd like a sequel, if only for the memes it would produce/address)
5) Killzone 5 (probably going to get some snickers, but yes, I like the Killzone series, though I haven't played past 2 yet. I know everyone loves Horizon, but there's still room for more Killzone in the world)
6) Perfect Dark (okay, the concept for Perfect Dark Core was rediculous, even by the series's standards, but that doesn't mean I wouldn't like a return to the setting)
7) Star Fox 5 (as in, not Zero, but a continuation from Command. Because lord knows that after Zero and Command, the series needs to get back on its feet)
8) Lost Vikings III/Blackthorne 2 (because I enjoyed Lost Vikings I, and if these get sequels, I get more characters in Heroes of the Storm. Cha-ching!)
...okay, kind of stretching things there, as there's some overlap with the original list. And speaking of overlap:
Warcraft IV will probably never get made. It just wont live up to the hype and expectation.
For what it's worth, there is some hope for Warcraft IV, or at least, more hope than there was a few years ago. We know that David Kim and Dustin Browder have been transferred to work on a new project within Blizzard, and while not necessarily Warcraft IV, or even an RTS, both do have experience in the RTS genre (both were the top dogs during SC2's development). It's a slim hope, but a hope (for me) nonetheless.
