Whatever the merits of their claim, it is unlikely to be either "fast" or "bucks". The links I gave illustrate why this kind of "forum shopping" is unlikely to be successful.
The flip side of this coin, is that the forum this case is likely to end up in, will result in a painfully long case that will favour the defendants and simply wear down the complainants. There is almost no punitive risk to large corporations, insurers, or those with deep pockets. This is why they will ensure that they forego the "convenience" of the chosen legal forum, to ensure it is heard in one where, even they lose, it will hardly matter.
