The sniper is a gamers board,not an enthusiasts overclocking one,you are paying for the sound card,
Indeed you are paying extra. However the two board designs are basically the same: If you call the UD7 an "enthusiast's overclocking board", so is the Sniper. Ultimately, it's all about economics. If, from Gigabyte's point of view, the Sniper has been comprehensively outselling the UD7 since the former board was introduced, then it makes little sense to keep manufacturing both, especially when they're both due to be replaced by the newer chipset stuff in fairly short order. It probably has as much to do with stock levels in the channel as much as anything else. Daresay they've all out of production at the factory now.
and the p67 ud7 is still around,and has been for a long time,so several months for a flagship board is dissapointing,hence i now use Asus.
Eh? You started this thread by complaining about the Z68X-UD7 being EOLed, and are now claiming that the P67 board is somehow different/still around. It isn't. The P67 line isn't "still around", it went out of production and was EOL months ago - they were replaced by Z68-based products. If you can still some at resellers, they're old stocks hanging round from the early part of last year.
However does it really make any difference how long the particular board is sold for. As long as they maintain support in the form of BIOSes and drivers for it I don't see that it makes any difference. 
Hmmmm, let's not dwell on this "maintaining support" issue too long. It would be helpful if GB would release one that fixes the various debilitating power management (i.e. POST-loop, cold boot etc) bugs, let alone some of the less serious stuff.
