I seem to vaguely remember posting this over a year ago, and the release was previously put on hiatus, but now seems likely that it will get a release this year
Originally due out last autumn, it is now due to be released on the 1st of September 2011 for £59.99 - I've personally had this held as a pre-order with GAME since last June!

No word whether the model included is die cast, or whether it is just a cheap plastic moulded model, although I fear for the latter if other CE's (Eg, Mortal Kombat) are anything to go by... It's deceiving, as it appears to look like a die cast model, but I suppose such a thing would make the CE far too heavy to realistically ship
