Help on whether it's worth getting the 3DS with Ocarina of Time?

Just wondering whether or not it was worth it. I currently have a voucher that lets me get the 3DS along with Ocarina of Time from GAME for 180quid. On top of that I have store credit of 20quid so overall it would be costing me 160. I'm already keen on the 3DS and love the game as I've played the original - but my problem is whether or not I should wait for a further price reduction or an upgrade to the 3DS which possibly could be due out next summer? The voucher which drops the initial price by 30 quid is ending in a week so I need to make a decision now?
