My best bet is to get a Yamaha soundbar, they are awesome, i own one myself and very pleased with it.
Otherwise there is allot of new one's coming from various manufacturers i think, one for sure is Panasonic, this will be the 1st time they have made soundbars and prices are very keen too. There will be 2 models, the 1st one is a: SC-HTB10EB-K which is a soundbar with integrated subwoofer, 120 watts, HDMI with Dolby TruHD and DTS HD Master audio too, retail price will be around £249.99. As for the other model which is the SC-HTB500EB-K, this will be the same system as the one mentioned apart from its 240 watts and with an external wireless subwoofer, retail price around £349.99.
