Yes, however, a) earth sized planets are very hard to find, as they are very small, and b) anywhere there is a gas giant planet, there exists sufficient angular momentum in the system for a high likelihood of other, less detectable planets. c) as close as this new planet is to its star, one of its moons, or even a small planet in a closer orbit would be large enough and warm enough to be at least marginally habitable/terraformable...

There are hints of small planets around some nearer stars (including Proxima Centauri, the closest star), but not enough redundant evidence at present to make a conclusive case. I expect by the time we are able to send probes out on such missions, we will have very good images of even earth sized planets within 100 or so light years thanks to the interferometry projects currently in the planning stages.

The smallest planet found so far is I beleive 3 times the mass of Earth, in an eccentric orbit around a star 35 light years away, accompanied by at least two other superjovian planets.

Things are starting to look up.
