Canvas 4 LockScreen

Today just got a image of Canvas 4 from Micromax Official Page,So here it is : 

Im a bit confused in this case,

On Left we see IPhone Lockscreen...
On Right we see a Blackberry Device with Blackberry LockScreen..

On Center we see Samsung S4 with Stock LockScreen,It is Android 4.2 Styled..

So Canvas 4 is 4.2 and may have better Lockscreen's than others .......

Still i didnt understand the use of the other three lockscreens..Did they put those to Canvas 4 or just they wanted to show that Canvas 4 Lockscreen will be better,

I think its just another image to tease us ...

8 DAYS LEFT FOR THE ACTION,Canvas 4 COMING ON JUNE 28th
