The Kobo Glo was originally launched in September 2012 and did quite well in North America and Europe. In recent years this e-reader was a bridge to overseas markets and sold all over the world. The Glo is now officially discontinued.
The main Kobo website now brings users to a 404 page when they try and purchase this low cost e-reader. This is the same thing that has occurred in the past when the Canadian based company discontinued the Kobo Mini.
Kobo currently has two openings in their product portfolio and they are actively developing the next generation of e-readers. Their codenames are Alyssum and Pika.
The Alyssum e-reader will be six inches and have a resolution of 1072 x 1448 and 300 PPI. This is very similar to the e-reader that Amazon released late last year, the Kindle Voyage. It is very likely that Kobo wants to heavily compete against Amazon with very similar hardware. Pika on the other hand will supplant the Mini, which was discontinued in 2014. It will be five inches and have a resolution of 800 x 600.
