MD have indeed brought out two new machines. However they as yet do not appear even now to fulfill the lavish specifications presented on the MD website/brochures (*USB sound and microbus on the Mico, USB, graphics acceleration, networking, UDMA IDE interface X-Scale and X86 second processors in Omega etc etc) despite having several years to do so.
Castle have admittedly brought out only one completely new machine** which functioned as described out of the box a year ago, without pre-announcing it or asking for deposits.
A bird in the hand is worth two in the bush.
* feel free to correct me on any of these.
** oh and two half new computers the Kinetic 233 upgrade and the Kinetic 300.
