I went a bit mad:
2x Stonehorn/Thundertusk
2x Ironblaster/Scraplauncher
3x Mournfang Cavalry
Lordy! What a maniac-I'd hate to be facing that lot from the other side of the board....

I'm still waiting on mine, but personnaly do think the discount makes it worthwhile for me at least. Yep I'd have liked them alot sooner, but there's nothing I can do so have to be patient if I wants me stuff.
I do think it's GW holding back on supplying, and that this is not unique to Wayland. I guess GW wanted to see the stuff fly out of their stores first and make more money rather than just getting the trade price from other retailers, which as it's their baby is only right (for GW anyway). In the meantime independent suppliers awaiting stock have to bite the bullet and get the backlash from peoples who have placed pre-orders such as many of us.
The independents are caught by the short and curlies in many ways. They can't supply to pre-order peoples as their suppliers haven't supplied them yet as they're supplying their own stores first. Common sense from a business view for GW in many ways.
Just crap having to wait eons for the stuff you've pre-ordered and expected to arrive within a day or two. May be supply just couldn't keep up with demand and poor Wayland ended up with more orders than anticipated. A discount can be a double edged sword in many ways.
If you check on the Maelstrom site alot of the OK stuff is not showing as being in stock, so either they've had them and sold out, or not yet been supplied by GW.
I like Wayland and I like Maelstrom and have always had perfect service from both so I'm not worried about waiting a week or two longer. If they say it's been dispatched and I haven't got it a week or so after that, then other channels must be pursued.
Still itching to get my hands on my Ironblaster/Scraplauncher and mourngangs mind you. I'd ordered one of each then got tempted and ordered another
