Might be.
All I can do is wait. To see reviews and later get some hands on time on the new MacBook.
What I said is that I'm confident that it will handle Adobe apps well without many hiccups while being noticeably more portable than rMBP.
Are you going to wait for reviews or order right away? I'm ordering right away, but I'll hold off on selling my rMBP before I try it out. But I am sure it'll handle my usage.
