The new LEGO Store Calendar for the month of April 2011 is available and there is some interesting info on the actual release of Series 4 of collectible minifigures.It will therefore be possible to find them around April 15 in the USA. More surprisingly, the blurb clearly mentions "These limited edition minifigures won't last long" which can be interpreted in different ways.
But above all this type of discourse confirms that LEGO maintains the effect of exclusivity and shortage around this range, at least on the marketing level, but also in the field of availability as seen in the previous series.
Note the release of the Ninjago game on DS on 12/04 and that of the Maersk train on 25/04 for those who are impatiently awaiting it.
