Can you not remember PS3 at launch. I can.
It released in the UK with 7 games. Nothing really happened until Uncharted then shit went crazy. At one point I wish I didn't sell my 360 so soon to fund for the damn thing lol
PS4 as already had plenty of games and new IPs. Knack, DriveClub, The Order and Bloodbourne. 2 flopped (The Order still awaits personal verdict), 1 rebounded back from a flop (I still enjoyed DC from launch) and Bloodbourne got it right. But they are still trying new franchises plus there's a few known new IPs in the works.
They have also released good solid exclusives for a console not even 2 years old. KZ, LBP, MLB, I:SS (enjoyed them all, KZ mp has always been very fun to play) and Uncharted 4 is only around the corner.
To top it off PSN is better than ever, PS3 had a shocking store for years.
If PS4 had had a "slow start", then god knows what you would call PS3 early days.
