Question about buy ShB for PS4

[xvshanevx]

So, I recently bought a PS4 Pro, and am thinking of getting ShB on it.

I currently play FFXIV (With SB expac) on my PC, which is trash. I am thinking of buying ShB for PS4 but I am unsure what all I need to buy. I know I would need to buy the FFXIV Starter Addition, and that HW comes with SB.

Question: What I am wondering is if I buy ShB+Starter would I have access to SB when ShB goes live? Or will HW and SB come packed with ShB?

I don't mind continue play on my PC until then, but would like to make that jump over to my PS4 without having to re-buy SB.

Also, more importantly, due accounts transfer from PC to PS4?

EDIT: I just have to state, it is quite stupid that you have to purchase separate copies like this.
