IKEA's announcement of plans to release a TV and entertainment system integrated into a piece of furniture has garnered heaps of coverage. However, those devices won't hit markets outside of Europe until 2013.
The Uppleva range, which incorporates a built-in Blu-ray player and speakers as well as the T, is hitting a handful of European countries in June, and is said to be reaching IKEA's other markets in 2013. Whether IKEA will want to produce TV hardware specifically for Australia is an open question, though that should largely be a question of the power supply.
While the idea of hiding away cables is tempting, I'd tend to shy away from this kind of integrated solution, since the furniture is less flexible if you decide to get a different TV (or the hardware breaks down). What do you think?
