Really not sure what to make of this, DSE are accepting pre-orders for GTA V for PC:
DSE GTA V for PC with a supposed release date of 30 June this year.
Now unless I've missed a few tricks, the GTA V release date for the the two 'big' consoles hasn't even been announced yet, let alone the PC port (I hope I'm wrong). This lagged by 9 months or so for GTA IV if I recall correctly.
Seems a bit cheeky. Alternatively I guess if you paid your $99 and it turns to retail at $150 on release I guees they'd have to honour it.
