If you mean stuff like all the cool online exclusive infantry we've been getting, I don't have a picture handy, but they are bigger than the old infantry. The same is true for the newer battlearmor minis. The new stuff is sculpted at roughly 10mm scale, rather than 6mm 'mech scale. That was done as an intentional choice to allow better detail on the models, at the expense of ideal scaling. (Some of the bigger BA is nearly protomech sized)
Personally, I would have preferred them to be a bit smaller, but they are very well done, so I can't complain too much.
