There are some releases which should be released even before Prague '11. Coldharbour releases are every 2 weeks so this is my assuming:

3 January: Coldharbour Selections Part 25 [CLHR109]
17 January: Markus Schulz - Future Cities [CLHR110]
31 January: Mr. Pit - Stamina / Overload [CLHR111]
7 February: Rex Mundi - Valley of Dreams [CLHR112]

I think these are all unreleased tracks before Prague '11!
