I noted in the Sightings section last week that BBTS had just stocked the second wave/series of the blind-bagged Kreo Microchangers, and now that they have appeared in American stores, we have some confirmation on the names and the code numbers on the backs of the packaging.

(names are the same as those given out at the US Toyfair, but BBTS have some images mixed up with Wave 3)

66 - Bulkhead
67 - Hardshell
68 - Blight
69 - Arcee
70 - Acid Wing
71 - Vehicon
72 - Scourge
73 - Powerglide
74 - Perceptor
75 - Lugnut
76 - Hoist
77 - Groove

Note that the box is blue with Wave 2, to easily identify it. It is also likely to be smaller than Wave 0 and Wave 1, as they had 32 bags in them, and Wave 2 (and 3) apparently only have 24. (hope that means there is a complete 2 sets in each case)
