ok from what i can tell (and a lot of this is breaking the cardinal rule of 40k... I.E. apply common sense to rules interpretation.)

You can use the old termie bases. as the rules specifically say "The Base a model is Mounted on can be NO SMALLER than the base the model was supplied with."

IMO the old termie bases are still legal. what this does to squad coherency is minimal, but what it does to template weapons is very well, Ugly as fewer will ever be under it.

HOWEVER this is also balanced with the deep strike rule.

as you must put them in circles touching bases.... the smaller bases take up less space. so you have less chance of ever landing on terrain or other models.

My 2 cents.
