That's my first reaction to it too. But the MSRP is the same before the MF discounts. Both MF and XLN show the three instrument bundle for 179.00 I can't find anything on the XLN site that refers to a 'Promo' Studio Collection which made me wonder if that term is part of MF's sale. Also, on the XLN site it gives you the option to buy the offer as an online download version or from one of their dealers, which MF is listed there. I didn't see the offer on the site until just a little while ago and I've been all over it much of today.
Anyway, it appears they just added the offer and if we get it, all the better. If not, the deal for three is still excellent!
But at this point, I won't negate a little hope until I find out from them. :)
