Ok, the way I see this is as follows:
MLB is trying to make the market geared towards kids and such, but they have just alienated the older collectors like myself. I love the Bowman draft products, and even enjoy the bowman regular set. I was never a big fan of Upper Deck to begin with, but, I will admit, they have some cool designs and cool cards.
If this deal affects minor league card's such as Just Minor's and Tristar, then I will stop collecting, because these cards are my hobby, I have a few images that have been used on cards before, and I will say that I like the Just and tristar products better than anything topps could ever produce.
As for the verdict on this deal, I believe that some way shape or form, UD will be back, and Topps will not have cornered the market. Granted they have a ton of good product, and a ton of cool cards, I think that this is bad for the hobby, and I agree with the poser above, the bubble is about to burst and when it does, say bye bye to the card industry.
My two cents.
