See, I disagree with this. While advanced anti-tank weapons were a developing fear around the time that the build-up surrounding the Cold War began, tanks still had a purpose on the battlefield, because air power wasn't nearly at the level of advancement it is today. Now look at the First Gulf War. Iraq had a very large, very (regionally) advanced armor inventory, but they still got crushed.. by precision guided munitions, and aircraft engineered for the specific purpose of taking out tanks.
Now, also factor in a couple Sixth World realities. First of all, most major conflict would end up at an urban center - much like today - where the use of non-precision force is impractical; ironically, the same problem that has drastically reduced the effectiveness of artillery. Also, remember that for low costs (by military standards), you can implant regular infantry to be drastically more deadly, efficient, and survivable then their current equivalent. Finally, keep in mind that a small fraction of the population can learn hard-to-detect spells that are tailor made to either cripple or outright destroy vehicles. Contrast this against how effective, advanced and affordable drone aircraft are in 2070, and I think that spells their doom.
I think developed nations like Japan, the UCAS, and CAS would replace their tanks with lighter, more urban-friendly infantry support drone platforms, whereas third world nations would probably maintain their arsenals of older, largely ineffective tanks.

Iraq had no air force to protect their airspace. That's why I said "all other things being equal". There hasn't been any war fought between two modern armies in decades, only one superpower against some technologically inferiour foes.
Also, speaking of the 6th world, once collateral damage is no concern, the need for precision force in urban terrain lessens greatly. Not to mention that this vaunted urban terrain still needs to get supplied through non-urban terrain. Drones are only as effective as their computer network is safe. A tank won't be as easily taken over, and won't be limited to programming when cut off from communication.
