As expected Wii sales improved vastly in April. It is its third month of very high growth (was 90% in March and 72% for February). GTA4 didn't increase HD consoles' sales a lot but at least they didn't drop as hard as NDS, PSP and PS2.
This month changes:
NDS: - 25.5%
Wii: + 40.7%
PSP: - 10.8%
PS3: + 7.0%
PS2: - 28.8%
X360: - 8.6%
