Absolutely agree with OP. TS5 isn't going to much different, if any from TS4. DLC will get stripped back further. They probably will make sure that they launch with better babies and toddlers. I wouldn't be surprised to see the colour wheel back for skin, hair and eyes.
I'd have to see how reviews pan out before I make up my mind on it. I certainly didn't just toss TS3 aside for TS4. I didn't even get TS4 until after the toddlers were patched in. I was excited when TS4 was announced (much like every one else) but when I saw that base game... :/ I really don't think TS5 will make that mistake again, but I don't expect it to be ground breaking anymore either.
