Faster bearing speeds, which would create more heat, and more likely to spin if you rev it high, but I do not know how big is to big.

Yes the bearing speeds will be higher BUT there is also a greater surface area to take the force. The oiling properties have MUCH more to do with durability at higher speeds than just bearing diameter. You can't tell from those pics, but the X rod may be wider too, which would create even more surface area.

hard to tell from just a picture, maybe they are a bit wider which will put less load on the bearing as a whole. Time will tell i guess. There are pro's and cons to the new 4b11 just like any other engine.
