I notice on the German Gigablue support that Gigablue are announcing two new models; the SE+ and UE+.
From what little was written it appears that they will have the same CPU as the quad and be able to take the new S2 plug-in tuners to get a really cheap, fast dual/triple tuner receiver.
They also announced a new remote with keyboard and a USB Gigabit adapter (which looks like an OEM based on the ASIX ax88178 USB2 chipset)
The new boxes will be ready in August, the pluggable tuners 'sooner'
