The problem with the LAV 6.0 upgrade is that it isn't really an upgrade, more a stealth replacement (much like the Royal Navy's through-deck cruiser). New hull, new engine, up-rated suspension, larger tires, new seats, most of the expensive bits of the turret replaced - there ain't a lot left. Mainly the 25mm Bushmaster cannon. One thing it won't be is cheap.

Agree on the urgency of the Armoured LOV replacement (the unarmoured ones work OK). My thinking is that it's replacement requires two new types of vehicle (for our international peacekeeping effort).
1. A mine-protected 4x4 light armoured patrol vehicle, with a crew of 4-5. There are plenty of such vehicles currently on the market (eg. Oskkosh JLTV, Australian Hawkei, the BAE RG Outrider LTAV- with the Irish Army). Could also be used as an infantry battalion recon vehicle.
2. A larger utility MRAP in a wide variety of variants to cover multiple roles - but especially for the combat service support & combat support units. eg. Thales Bushmaster, the UK Ocelot etc.
Wouldn't expect huge numbers of these - enough to cover 2 rotations of a company group would probably do.
Finally, +1 me on the Bronco / BVS10 Viking vehicles. Just the thing for puddling about in Pacific Island lagoons. More of a LVT4 amphibious tractor type than an assault vehicle.
