It has a meaning, but it can only be told for sure when the gen is definitively over. Also, not necessarily a whole gen can be front loaded or not, each of its platforms can or cannot be so. During 7th gen, IIRC, Wii peaked early while PS3 and XB360 did it later, but XB360 also had an earlier lower yearly peak, followed by a small drop, then it recovered and had its second and absolute peak (PS3 instead grew steadily without yearly drops, so it had only one yearly peak).
