Forthcoming Kobo devices

Hi, I currently read my ebooks (mainly epubs) on my iPad, but I would like to buy a more compact device to read outside.

I've just noticed that Kobo Mini and Kobo Touch are sold at a huge discount and I'm really tempted to buy one of them, probably the Touch.

Before placing my order I would like to know why they are selling those two models at lower prices. Are there some new models in the pipeline?

Can you suggest me a website when I can read some "rumors" about forthcoming Kobo devices (think of macrumors for the Apple universe)?

Thanks
