These are predictions I have made based on logic of the current META as well as upcoming structure/booster sets coming out. Noted some of your opinions may differ from mine, feel free to comment your ideas bellow.
Banned
Evilswarm Exciton Knight
Too splashable in most decks, most overused and overabused card in the current META
Hieratic Seal of the Ashes
I can see Hieratics being hit, and I think this is the perfect solution. It is too abusable with Dragon Rulers which Konami simply will not let die.
Rekindling
A hit for 3.4 Fire Fists and solves the splashability in Fire Based decks.
Limited
Abyss Sphere
One of the 2 cards I think will be hit in mermails, the card is nuts at 3 and cutting it back to 1 will help slow the deck down in pace with the current meta
Elemental hero Stratos
New Hero Structure deck support, I thinki Stratos to 1 will hype this. It never deserved to be banned in the first place
Elemental hero Bubbleman
I like how the OCG dealt with the problem of the Hero OTK and I feel that the TCG can also follow suit
Geargiagear
As the most stable OTK I expect geargias to get a hit. Gear is an instant +1 not to mention all the shinanigins you can do off of geargiano. Also ahead of support though so again maybe one for next banlist.
Madolche Hootcake
Pre Anjelly release - this may be 1 banlist too early but madolches will need to be hit in the future. I think Hootcake at 1 makes the deck cope-able - besides it can still recycle it
Silent Honors Ark
Rank 4 splashable permanent mind control which any rank 4 deck can abuse. It being put to 1 is the most sensible think konami can do.
Semi-Limited
Bujini Crane
Enough of this guy at 3...4 Honests in Bujins is overkill
Coach Wolfbark
I do not think Wolfbark will go to 1 as it is being released in gold series later in the year, but it is the most sensible option to semi-limit in fire fists. It is either this or limit bear which would just kill the deck.
Dragon Ravine
It was harsh to send it to 1 as it basically killed dragunities. Unlimiting it will spark more Ruler plays so I feel it has a rightful spot at 2.
Mermail Linde
Second mermail card I think they will hit, again it does not kill off the deck and it can still get some pretty nasty plays under-way
Skill Drain
With the amount of effect based decks going around, I can see this happening, although I am not too sure.
No Longer On List
Lone Fire Blossom
Konami are hyping Sylvans, If this happens I will have to kill them, but I think there is a possibility.
FURTHER POSSIBLE CARD HITS (NOT INCLUDED)
SHOCK MASTER (some people are rumouring this to come back to 1)
INFERNITY BARRIER (seen this placed at 2 in some banlists, but I think infernities are too much of a rogue deck to hit quite yet.)
DARKWORLD SNOWW (pretty much same as barrier)
JUDGEMENT DRAGON (people are anal about lightsworn sacks, I have seen some lists where he has been banned or placed at 1, particularly with the new wyvern craze.)[/color]
