This has already been beaten to death here recently. It amounts to a drop in an almost-empty, leaky bucket. Lomo shooters won't make any difference and won't turn the clock back for film.
No-one would be game enough to say that film will come back to dominate the photo market, that would be foolish. There is no doubt digital is here to stay and will command the majority of the market, however as amsp pointed out a revival of some sorts for film seems to be happening. A decade ago you could pick up a good quality film camera and lenses off fleabay for next to nothing because the digital excitement was growing, that certainly can't be said nowdays. Good quality and high end film cameras are actually appreciating in price and fetch a premium. Proof, I just sold all my Leica M gear which I only owned for three years for a healthy profit, and that has allowed me to get into LF

In a curious unexpected consequence digital scanning has helped to keep film alive, you can still have the beauty of film and the convenience of a digital image. I asked my local pro lab operator about the demand for film or lack of it, he said it was healthy and they had no intention of getting out of it. The point about someone picking up the gap left by Kodak and Fuji if they completely fold is quite relevant, I would suspect that would come from China or maybe India.
While the plastic camera market might be a "drop" in the big scheme of things, at least it is something and without the actual figures its hard to say if the bucket is leaking or filling. I can say from knowledge though that there is a healthy demand for film with Australian university students doing arts or photography because they are forced to learn how to use a real camera, most will probably move into digital but some will continue with film I suspect because of its aesthetic value.
