GTA 5 to includes tanks, trains, bikes, boats, planes and cars

In a bizarre turn of events, some dedicated individual has sniffed out a vehicle list for Grand Theft Auto 5 via the Max Payne 3 disc.
Rockstar has been known to included data for other projects on their games, with the Red Dead Redemption disc also including GTA info. 
Included in the list found on the Max Payne 3 disc is a tank, motorbikes, pedal bikes, helicopters, trains, planes, a wide variety of cars and various types of boat.
So, planes, trains and automobiles, then.
The below list is not everything that was extracted from the files, but it’s a decent look at what to expect.
See it after the GTAV trailer.
