Mod Tools 1.0... hmmmm. I am still of the opinion that these tools won't be as in-depth as modders are used to.
Now, let's get down to the facts: there are 2 active members in the modding community (by active, I mean still posting in community modding forums) who actually work at Treyarch as developers, and one of them (Sparky McSparks) is actually on the mod tools team developing them. As with all things, they are under an NDA so can't say anything overt about the tools, but both of them have hinted at the situation to various community members who are their close friends, and the general impression given by these hints is that the tools will include Radiant, and we will be able to make multiplayer maps, along with SP and Coop maps in much the same way as we did before.
Apart from these 2 developers, I happen to be on good speaking terms with a senior producer at Activision. Again, an NDA prevents him from saying anything overt, but again he has hinted to me that the problems that PCDev first thought of as being big hurdles to releasing a stand-alone Radiant, actually turned out to be not such significant hurdles after all.
In fact, from what I gather, the real upset as far as mod tools goes doesn't actually even affect mapping at all - it affects modding: we wont be able to mod anything to do with the stat-based system. So, no mucking about with create-a-class, no fiddling with the contracts or COD currency, no modding the wager matches. That means, from the sound of it, we modders will have a bit of a battle trying to get all weapons unlocked for unranked servers.
So, as it turns out, the famous words of PCDev about the "technical difficulties" with the new Blops engine, and how he feared it might limit what we can do mapping wise, which have caused so much speculation and debate in the community, were actually said too soon. If he had waited until post-launch, when he had had the chance to examine the situation more closely, he would have been able to avoid saying it, and have avoided all this heated debate and controversy.
People can choose to believe me on this or not. Frankly, I don't give a crap. Never have done. However, I will be proved right regardless of whether or not people believe what I say here and now about the tools by the product that gets released. Then, people might catch themselves on, and admit, reluctantly or otherwise, that I did actually know something about what I was talking about.
