Contrary is going to get Serp banned. Just saying.
I won't be part of this because I have other priorities, but I will say I don't expect much from Omanyte. 35 base HP and four fairly common weaknesses do not bode well for the little fellow. With B2W2's omnipresence of Giga Drain, and the existence of powerhouses like Zangoose, Cinccino, Eelektross (might I add that I don't see enough of the poor fellow), and special tanks like Gardevoir and Gothitelle, hell, Seviper and Heatmor get Giga Drain and the special power to outrun and mow down Omanyte. If it wants to run all three hazards, it's left with being completely walled by anything with Storm Drain or Water Absorb, or it can run its only Rock-type Special move (granted, there's what, two of them total), which has 8 uses and poor coverage. Ice Beam is more viable type-wise, but it's weaker without STAB.
This thread isn't about speculation on future DW releases, nor what they're going to do to NU.
Yes Omanyte has a base 35 HP stat, did you also know it has a base 100 Def stat and normally runs Eviolite (which gives it nearly 500 defense points)? Yes, Omanyte has common weaknesses, but the point of Omanyte is that it can run Stealth Rock + other hazards. In my book, the trade is worth it. Furthermore, ever see anyone keep Garbodor in on a Psychic-type? Glalie on a Fighting-type? Cacturne on a Bug-type? Likewise, don't send in or keep Omanyte in on something that it's weak to. Omanyte gets plenty of opportunities to come in (resistance to Flying and Normal-type moves is a very good thing), just don't be stupid and throw it in on Amoonguss and you'll be fine. Storm Drain and Water Absorb aren't all over the place, so that next bit was kind of silly. Omanyte's base 90 SpAtk stat isn't that bad without investment, and Scald 2HKO's Armaldo and Torkoal (Torkoal is actually outsped by Omanyte as well, meaning that you can kill it before it can spin with decent prediction) as well as many other things weak to Water with relative ease. Let's not forget that nifty Burn chance, which would make physical attackers virtually useless against Omanyte.
0 SpAtk Omanyte Scald vs 0 HP/0 SpDef Armaldo: 65.98% - 78.35%
2 hits to KO
0 SpAtk Omanyte Scald vs 248 HP/8 SpDef Torkoal: 61.22% - 72.59%
2 hits to KO
0 SpAtk Omanyte Scald vs 0 HP/0 SpDef Heatmor (-SpDef) : 80.06% - 94.53%
2 hits to KO
If Omanyte predicts correctly, standard Heatmor is killed on the switch, although I don't know why anyone would switch a Fire-type into a Rock / Water-type.

It's not as bad as some would speculate, give Omanyte a try.
