Why PS3 Still Behind Wii and Xbox 360

I will not make a long post here but all you read lately is Wii break records or PS3 is not doing well.Well let’s look at it differently and you will realize its normal PS3 is not doing well.
Let’s see right now:
-Wii and DS are doing well because all focus on Gamecube and GBA gone.
-Xbox 360 is doing well because support or releases for original Xbox gone, but.
-Sony PS3 is walking the line with PS2 which just make it hard and on top PS2 games still being released right now up until June this year.
In my opinion Sony need to cease game releases for PS2 and focus on PS3 but then try and find a way for PS3 owners to play PS2 games or start selling PS2 games on PS Store.
And one plus PS3 have over the rest is , so far hackers havn’t been able to break it yet, so everyone playing at least PS3 games is legit while there’s modchip all over the net for X360 and Wii.
They said you can’t follow two path at the same time.
Now i say if PS2 is out of the line those report and analyses can be 100% accurate because right now it’s like 2 vs 1.
The report should go like PS2+PS3 vs Wii , not just Ps3 vs Wii or x360 vs Ps3
[update] Seems a hacker have found a way to play PS2 games on PS3, Sony need to get this to work legally not some hackers program which can break down the unit, we want official tool.
Am not a PS3 fanboy so please keep comment relevant to the topic.
